As I understand it, one of the problems with modern Transformers is they CAN'T use real-world vehicles, at least in America.
If I recall, a few companies threatened lawsuits over Robots in Disguise if some details on the toys(like distinctive styles of headlights/taillights) weren't changed. The companies that make cars and trucks and things that go don't want to be associated with toys, and WILL sue over it.
Hence the whole Beast Wars thing.
I see Armada as a step forward. At least we HAVE vehicles again, even if they're silly vehicles.
Of course, I haven't bought a Transformer in ages. Early Gen2. The whole resurrection thing came as I was deciding I'd outgrown my toys, and I haven't really gotten back into them yet.
Little things like new He-Man's Battlecat(Guns on Battlecat? Errrr, no.) and PC Megatron(DAMMIT, HE'S A HANDGUN!) help me keep irate enough at them to avoid that money hole/trip down memory lane.

Maybe I should thank them instead of ranting.
