Okay so we have Optimus Prime. Theories on the others, the Bugatti is suppose to be Drift and the Corvette is suppose to be Slingshot. That could be Ratchet in the far back, the new truck could be Hound, they were hinting at him. Lastly that may be new paint job Bumblebee, but many say it's the main characters own car.
I wonder who the big dark green truck is nex to optimus. Hound is that you?? It better not be ultra Magnus. also u can see an ambulance behind it.... Well we are getting another big bot sweeet!
SFTE confirm that the Camero is Bee.... That isn't the cab over truck we saw yesterday behind Prime... And just what is behind them all?
The big old looking truck beside Prime and the police car/suv are new additions. Hopefully Prowl is turning up or maybe the vehicle is an ambulance and is red alert.
The Ambulance could be Ratchet, but I hope it's Prowl. As for the green truck. Couldn't be Hound, it's too big. And It's hard to believe if it's a Dinobot like the other truck.
Looking at them all lined up like that, it's almost like this is the movie's generation 2. I'm guessing Bulkhead and Red Alert. On second thought that's probably just a facelifted Ratchet ( behind 'Bulkhead').
