What I've noticed so far with the TF Prime line (both FE and RID) is that there seems to be two scales portrayed by the toyline, excluding Cyberverse. (I'm pretty sure that several of you have already figured this out, but I'm just throwing it out there.) In one scale, arguably the most prevalent one, is the one that centers around the deluxe Autobot and Decepticon cars as being in the deluxe scale would mean that they're roughly the same size as the case in the show. In addition to the deluxe cars would be voyager Bulkhead (both versions), Breakdown, and Starscream as they have been shown to be taller than their deluxe compatriots (in the show and in the toyline). However it can be argued that Starscream is still a tad bit too tall, but fits in better with this scale than the deluxe would (I'm pretty certain that Bumblebee is not as tall as Starscream when Scream's been shown to be as tall as Bulkhead who's taller than Bee i.e. FE Starscream vs. FE Bumblebee). Arcee and Airachnid (most likely) would also fit in this scale in terms of robot mode. Cyberverse Arcee scales pretty well in vehicle mode. (Weaponizer Prime may or may not fit as well, though I have nothing to support this statement until the toy comes out) As for the other scale, it centers around voyager Optimus (RID and FE though the FE is a tad bit too big, YMMV of course) and Megatron. In this scale would also include the voyager Dreadwing/Skyquake mold as Dreadwing/Skyquake was shown to be of the same statue as Optimus but a bit shorter than Megatron. Being a voyager allows him to be roughly in scale with the two leaders, but we'll have a better idea once the figure is released. Along with those three are deluxe Ratchet, Soundwave, and Starscream. In terms of Ratchet and Soundwave, they're pretty much a perfect fit for this scale since Ratchet was shown to come up to Prime's chest (right under the windows) where as Starscream and Soundwave come up to a similar area when next to Megatron. However in this case, the deluxe version of Starscream also ends up a bit too tall to be in perfect scale with the others, but that just seems to be the case with Starscream. This only leaves Deluxe Prime and Megatron as the odd bots out. As for the Cyberverse, they seem to scale pretty well in robot mode (for the most part). Now, I'm interested in what you all think about this. While sure, scale and Transformers never really works out, it still remains a fairly important factor in many collections even though it's very possible to enjoy a fun TF figure without having to worry about scale. Any thoughts?
