bay,i hope you do conisder frank welker and peter cullen to redo their roles as optimus prime and megatron,both have said in numerous interviews that if givien the chance,they would do the voices for characters once again. I know there are a few people who disagree,but i think it would be really something,for those of us who grew up with the original transformer series in the 80's,to once again hear the voices that brought the 2 most famous robots in the world to life in your movie.
