Leaked out to the interwebs, I saw this at AICN which led me to bamkapow.com for some possible spoilers for the new Transformers sequel called “Transformers: Revenge of the Fallen”

From bamkapow.com:

Transforming Characters:
Arcee – a motorcycle (which, for fanboys like me, we know is named after the only female Autobot in the original Transformers: The Movie)

The Twins – an Ice Cream Truck, which sounds incredibly goofy, until you read the description of what they do…

Stinger – possibly a Porsche, but unconfirmed

R8 – character’s name is unknown, but transforms into an Audi R8 (I knew Tony Stark wasn’t the only one who’d have one of these)

Wheels (or Wheelbot) – possibly some kind of Go-Kart (let’s hope it’s not like Wheelie from the original TF…most annoying Autobot ever, besides Blurr)

Jetfire – a Blackbird jet (which again, is just plain AWESOME that he’s in this)

“Constructicon Earth Mover” – name is unconfirmed, but if that’s true, we’ll probably get Devastator (Constructicons, not the tank in the first movie)

Human Characters:
Josh Duhamel and Tyrese Gibson will return, as will of course Shia LaBeouf and Megan Fox. Added to the list are Matthew Marsden, Andrew Howard and Ramon Rodriguez. Also, LaBeouf and Fox were scheduled to film at the Smithsonian Air and Space Museum in Washington, DC June 5th and 6th. The scene seems to center around searching for something in the museum related to the Decepticons.

Aw man, I missed them at the Air and Space Museum. Although I doubt I could have just “walked up”, you never know. Would have been nice to find out before hand and convienently been sick that day…
