Yeah, we can finally see some of the numerous changes to the characters. Bumblebee does have more armor on his shoulder's upper arms (and his old shoulder armor looks slightly differently shaped, which is what I think makes it look beefed up to that other poster), the obvious chest mods, and his forewheels have moved from his rear-shoulders to his rear-waist. (
Prime's changes seem to be much more subtle (smaller pieces moving less noticeably), granted I am not as acquainted with his old designs as some other characters. Basically though Prime's silhouette will remain the same, which cannot be said for Bee.
I'm also rather surprised at how uni-thick each panel piece appears to be. They don't have the depth (especially the changes in depth) I appreciate greatly on movieformers alt-mode plates. It makes them look more fragile here.
And I agree Bee's mask is ugly...I don't expect them to be able to pull off each little feathery piece, but it IS rough, and they didn't even take off the armor on his head which is supposed to be said mask, lol, continuity.
However, overall I agree that these are amazing (sorry all you non-transforming transformers folks), and I would buy them in a heartbeat if I ever saw them on this side of the world. Alas, it's likely not to be unless someone has them at Botcon.
Also, I wouldn't be surprised if someone modded one of these to actually transform. Mmmm... :9
