Well we happen to know that Peter Cullen is pretty much, the only recognizable guy from G1 who happens to play Optimus Prime. But who else do you think should play voices for characters? My list consists of. Either Corey Burton or David Kaye should play Galvatron if he appears in any of the sequels. I think Scot McNeil or Gary Chalk should play Jetfire. And of course, nobody does a better Soundwave but Frank Welker.
