Jazz: Definite buy for me. I loved WFC and Jazz has always been a personal favorite of mine. Also the figure does look really good, very accurate to the game model. The only bit that really bugs me is the fake wheels, I mean, there was really no way to avoid that? Might just be that I'm still miffed over the eight-wheeled weaponizer Prime Bumblebee. I do wish the game model was a little more G1 though, specifically the wheels being on his shoulders instead of his forearms and something about the head seems off to me.
Shockwave: Hands down must buy. Best of the FoC we've seen so far I think. I especially like the apparent integration of his weapon into his alt mode. The only thing that worries me are the legs, they look a bit flimsy compared to his upper body, much like WfC Bumblebee. Also has anyone else noticed Has/Tak cutting back on the poseablity again, specifically in the wrists and feet?
Optimus Prime: Like many I prefer the WfC model to this new, bulkier, boxier version. It seems like they're pushing the "big and totally a truck" a little too much. Also the transformation looks to be abusively simple, as opposed to the WfC toy's interesting complexities (I love the little moving bits for the shoulders). Really on the fence for this one. Oh, and the gun looks stupid.
Bruticus: The Combaticons look pretty good on their own, and I will likely get them for that reason alone. Though Hasbro deciding on a good color scheme would really help. As for the combined form... it looks pretty bad to me. The biggest problems seem to be Onslaught's lack of mass and pair of horribly designed arms. The awkwardly spaced shoulder connections combined with the outright weirdly long and joined arms basically ensure that I will never have this set combined. The lack of a proper chest plate/crest and how outright hollow Onslaught's combiner form looks from behind certainly don't help the situation.
As a side note I hope that if these figures are indeed of the new, smaller 'Deluxe' scale, the difference is negligible enough so as not to cause issues displaying these alongside my WfC figures. I suppose at least it can't be worse that WfC Bumbleebee vs Optimus Prime.
