Interesting work but I would like to know whether you would find the amount of new sets offered in toto has changed over the survey period. Is there an economy of scale at work? This seems to have two implications: first, the number of units for a particular set may have increased thereby affecting the price of all sets belonging to that class (but doubtful you could find exactly how many Death Star sets were produced in relation to, say, hogwarts castles); second, the popularity of certain set classes may affect what kinds of sets are available. Like with language, we are all confined to use the words we know. And so with Lego, set designers are confined to use what’s economical, unless, of course, the design calls for new styled pieces. These relations are difficult to grasp in statistical analyses, but would seem to play a role in price steering.
The Transformers Animated series was broadcast internationally in 2008 except in Japan, where it aired in 2010. This new series uses a very different art-style from the previous series. The Autobots and Decepticons, while fighting in space for possession of the Allspark, crash-landed onto a futuristic Earth and resume their battle after laying dormant for years. In addition to the Decepticons, the Autobots have to face the human villains as well. Classic characters such as Optimus Prime, Bumblebee, Prowl, Starscream, Megatron, Jazz and Ultra Magnus appear in this series.
Although the character was redesigned to some extent, like the other characters in the film, many classic design elements remain in his robot mode including a predominantly red torso, primarily blue legs, the presence of windows in his chest, smoke stacks on his shoulders, and a head design influenced by the original, featuring the iconic faceplate and ear finials. The faceplate is able to retract to reveal a mouth. His weapons include his iconic ion blaster, a Barrage cannon, two retractable energon blades that extend from his forearms, which is a homage to Prime's energy axe in the Generation 1 animated series, and two retractable energon hooks that extend from his wrists. The trailer contains an energy axe, a shield, and flight gear. In the later IDW comics, he displays the ability to produce a holographic driver.

Undeniably, the most iconic of Bumblebee’s alternate modes is his original: the small but always reliable classic yellow Volkswagen Beetle. It was evocative of his personality, always striving to go above and beyond what everyone perceived to be the limits of his size. These days, thanks to the Michael Bay live-action movie franchise, he’s known as a modern Chevrolet Camaro, which looks cool but as a strong muscle car deviates from his personality. At least it’s still yellow? Bay says he didn’t want him to be a Beetle anymore because there was already an iconic movie Beetle: Herbie the Love Bug.
Virtually every toy in this list has a scannable insignia sticker on it. For Hasbro releases, it temporarily unlocks that toy as a playable character in the Robots in Disguise mobile game, and can only be scanned once per day. TakaraTomy releases simply check that off on their mobile app's collection list. It's honestly quicker and less redundant to say which toys don't have this feature. Meanwhile, scanning the Combiner Force toys' insignia stickers gives the player Tickets, which can be spent by giving them to Cryostase via the main map menu.

Ultra Magnus is a redeco of the Diaclone "Powered Convoy" figure, itself a redeco and slight retool of "Battle Convoy", the toy that became the original Optimus Prime figure, sporting a new trailer. One of the last few Diaclone toys to be released in the Transformers toyline, Magnus was recolored from the original toy's dark blue, red and black color scheme into a more patriotic red, white and blue, though his chestplate, which was rendered white in his package art followed a more the blue color scheme of his shoulders. He transforms into a Freightliner COE, towing a car-carrier trailer capable of transporting up to four normal-sized Autobot cars. As with Optimus Prime, his cab transforms into a small robot, which can then combine with the trailer to form a "super robot", although all original Generation 1 fiction prior to the 21st century ignored this and simply rendered the super robot as Magnus's default robot form. To facilitate this combination, Magnus sports a slightly longer front axle than Prime, thereby creating tabs on either side of the cab that slide into grooves in the trailer to help lock the small robot into place. He is armed with a rifle sporting two handles that allow either of his robot modes to hold it, and two shoulder-mounted missile launchers, whose spring-loaded firing mechanism was removed for the Hasbro release of the figure.
The values started becoming inconsistent and skewed in Generation 2 and Beast Wars, when Hasbro apparently thought no child will ever want a toy that is described as anything less than perfect. Thus it became rarer and rarer to see any low numbers. Most characters' numbers hardly ever dipped below 8, the Go-Bot version of Optimus Prime was the first character to have all values at 10, a trend that would repeat for most "leader" characters. When even more powerful versions of the Optimus Primal toy (such as Optimal Optimus) were introduced, Hasbro even invented a "10+" rating in an attempt to keep increasing the power levels. With the Transformers: Cybertron line a few characters even got "Unknown" and "Infinity" ratings.
This increase in average piece count could be a factor in why LEGO is perceived to be more expensive now than in the past. LEGO sets have become larger and more complex. They have started to market directly to an older crowd with sets such as the Modular Buildings and the Architecture series. These new sets have rekindled interest in LEGO for an older generation but at the same time, it has introduced this same generation to the relatively high price of LEGO sets.
One of the single rarest Lucky Draw Figures in existence, this "Custom Color" redeco of Super Optimus Prime was limited to only one in the world. It was the grand prize of a coloring contest held in Septemeber 2005's TV Magazine, in which entrants colored in lineart of Prime with the deco they wanted to see. The winning entry was in green, blue and gold, while ten runners-up received one of five gold or five silver Lucky Draw versions of Prime.
Part of the first wave of the 2015 Robots in Disguise line, Optimus Prime is a smaller-scale toy. He transforms from robot to trailer/truck combination and back! Like every Robots in Disguise Legion Class toy, Optimus features 3mm posts on his hands and arms. Due to the size and simplified transformation, he ends up having 6 wheels instead of 10. His scannable Autobot insignia is on his robot mode left shoulder. However, the badge is completely impossible to scan in vehicle mode.
A slight redeco of Takara's Deluxe-size Optimus Prime was released as part of a special set commemorating both the 20th anniversary of Transformers and the 30th anniversary of its progenitor, Microman. Coming with an exclusive metallic redeco of Takara's Kicker, which was based on the Microman body, this Prime featured a chromed grill where the original had painted plastic, and supposedly slightly shinier plastics. Very slightly.

This set's Optimusses are based on the Prime incarnation. The larger Optimus is a smaller, simpler build than the first big kit, and makes use of ball-and-socket parts for increased articulation. It also carries a spring-loaded missile launcher. The Optimus Kreon's tampographs are based directly on the Prime cartoon model, though he carries an energon axe akin to the one from the War for Cybertron games. He also has a clear-blue extra "energon" torso piece.
Optimus and Wheeljack returned to Autobot HQ after an absence to find Grimlock had taken leadership. Though they failed to resist him, he soon bored with leading the Autobots and let Optimus take command again. Me, Grimlock, King Impressed with Bumblebee's success as team leader, Optimus assigned Pipes to lead a team. The B-Team Part Deux With Optimus badly damaged and without the Matrix, the Autobots were driven off Earth and sought refuge on Cybertron. Once Optimus had recovered, he put together a team which returned to Earth and retook it from the Decepticons, with Optimus badly damaging Megatron in combat. All Hail Megatron

Part of the new Adventure Shokugan series, this Optimus Prime is a transformable snap-fit kit molded in red, blue, and yellow plastic with detailing from stickers. The kit's transformation engineering is borrowed from the Warrior class figure. But unlike the said toy, the Axe must be pegged onto Prime's legs before transforming, and his shoulders are molded on his front truck halves/shoulders not being flipped down. Also, the stickers are used to cover the molded cavity on the front shoulders. As with Fixit & Underbite, Optimus Prime is fully transformable.

Bumblebee had many adventures in his bizarre humanoid form. He wound up in the heart of Cybertron to find the resting place of the creator/god of all Transformers, Primus, and learn of their origin as a race. Later, he went on a quest to find the all-powerful Creation Matrix, also known as the Autobot Matrix of Leadership, but stumbled upon the Cybertronian Decepticon commander, Thunderwing, who blasted away Bumblebee’s Pretender shell.
Generation 2 Optimus Prime comes with all his original accessories, as well as two major new play features. To increase his arsenal, he is armed with a pair of black missile launchers that fit in his fists and fire red spring-loaded missiles; these launchers were retooled from the G.I. Joe figure Barricade. Secondly, he comes with an electronic "sound and lights module" that can either plug into the front of the trailer (where it resembles the air conditioners used on refrigerated trailers), or hook onto Optimus's back in robot mode (via a new slot sculpted into the cab robot). Unfortunately, the soundbox is heavy enough that doing so can easily overpower Prime's hip joints, causing him to topple backward. The soundbox features a large, vacuum metalized Autobot symbol on its front, and three grey buttons which trigger two flashing red LEDs on either side of the module, and a trio of sound effects: a truck engine noise, a laser gun sound effect and a garbled voice that said "I am Optimus Prime!". The module also features ports on either side into which the missile launchers can peg.
I don't have a really good pic and I probably have something more rare in a box somewhere that I can't remember but this is my fav 'rare' Transformer: https://s3.amazonaws.com/tf.images/reduced-image_4474_106.jpg Sorry I don't have a real pic, I am packing up to move but here is a stock pic of TF Prime FE Japanese Convention Exclusive Optimus Prime.

The TakaraTomy version, part of the seventh wave of Japanese Prime toys, is dubbed Arms Master Optimus, uses darker, metallic plastics, casts the backs of his thighs in metallic red, replaces his metallic silver paint with glossy gray, and replaces a few of his paint operations with customer-applied foil stickers, such as his insignias, shins, headlamps, the tiny yellow lights on his torso, and the blue deco on his truck panel sides. He has also been retooled with additional 5mm pegs for his thighs, roof, and lower backpack, as well as ports for his forearms, shoulders, smokestacks, fuel tanks, and roof. Instead of the rifle, he comes with a very large Matrix which can tab onto his chest as armor or mount onto the back of the truck cab, with the Matrix also being covered in 5mm posts and holes so that Arms Microns can be attached to it. He additionally comes with a clear-blue "Shining" version of the Arms Micron, R.A., who can combine with the Matrix to form the colossal Matrix Saber.
Optimus became the leader of the Autobots for a time, then disappeared, leaving his people to be ruled tyrannically by Megatron.Targetmasters Megatron never stopped seeking out his old foe, rewarding any of his troops that provided him with information that could lead to Optimus's whereabouts. The Golden Boys As for the Autobots, they were uncertain exactly as to why Optimus had disappeared; some believed Optimus had simply abandoned his troops, while other believed he was fulfilling some greater purpose and would return to them in their hour of need. Ultimately, it was Snake-Eyes and Duke who found the Autobot leader, lost in the void between dimensions. Form Follows Function There, the three of them became ensnared by the Quintessons. They escaped the extra-dimensional entities' mind-probe and made their way back to normal space. En route, Optimus learned from Duke that Bumblebee had traveled to Earth and met his demise there. His human companions went off to help their friends on Cybertron, while Optimus headed for T.H.E. P.I.T. on Earth, eviscerating numerous Coltonbolt satellites as he entered the atmosphere.

Part of the first wave of TakaraTomy Lost Age: Movie Advanced toys, this Japanese-exclusive redeco of 2007 Transformers Protoform Optimus Prime is given a Generation 1-styled color scheme (which is also based on his appearances in IDW's Transformers: Foundation comic-book mini-series). Protoform Optimus Prime transforms into his "entry" mode. This mode somewhat resembles a cybertronic truck, with false wheels sculpted onto the sides, and Optimus Prime's trademark windows in front. His now-blue flame decoration piece fits to the back of the "vehicle", creating the illusion of a flaming comet's tail (Not sure if this was mean to represent his jetpack blast effect or his atmospheric entry heat effect, which is for no reason: entirely blue instead of hot red). The bottom of the vehicle has small wheels to roll the toy across smooth surfaces.
