With the designs as different as they are, I don't think it would make sense to have Welker play Megatron in the movie. Bring up an image of movie Megatron, then play any of the old TF cartoons where Megatron speaks. Stare at movie Megs while cartoon Megs speaks and let me know if you think it sounds anywhere near correct. This Megs is too different from our Megs. It is more like an evil bug with than a robot. The voice should be done by the guy who did the voices of the Gremlins. (Unless Welker did some of those voices, then please let it be Welker). However, if they were going to choose him, they would hav edone so by now, don't you think? Welker has said he is still in the running, last I heard, not selected. I don't think we'll get him.
