Imdb.com's trivia page for Revenge of the Fallen states that there will be some original voice actors from the classic series returning for the film. I find this curious, since they're not listed as being cast in the actual cast list, or on their own official pages, but only in the trivia section. But perhaps it just hasn't been made fully official yet, and we'll see them listed in time.
First of all, Susan Blu, who voiced Arcee, will have a role, which I can only assume is, of course, Arcee.
Voice acting legend Michael Bell, also known for voicing Duke in G.I. Joe, has apparently also been cast in the film. In the original series and movie, he voiced Prowl, Sideswipe, Scrapper, and Swoop. Perhaps he will be voicing both Sideswipe and Scrapper in the new movie.
Another actor the page claims has been cast is Rob Paulsen, who voiced Air Raid, Skydidve, and Chase. All pretty minor characters, but nevertheless, it's another original voice actor.
I've never heard of Mr. Paulsen, but apparently he's beeni ina lot of stuff. I'm very glad Blu and Bell are back on board. Arcee's voice will be the same as it was in the series, which is good. I could care less what Sideswipe sounds like, since he was a pretty minor character, but Bell is such a big name, I'm psyched to have him aboard.
Here's hoping for the best.
BTW, here are some photos of Blu, Bell, and Paulsen, respectively.
