Transformers 3 set pics; New Cars revealed!

Comicbookmovie was able to snag a couple of cool pics from the Detroit(I think) shoot of Michael Bay's Transformers 3. I don't know what in the hell that crazy looking tank/battlestation/pod racer thing is in the first two shots, but I'm gonna go out on a limb and say that it's a Decepticon. I wanna know what's up with that truck it's headed towards. If only that were a live-action Ultra Magnus...

The last couple of pics could possibly be the Stunticons in action. I hope so, anyway.
