Disney's so careful nowadays with their own characters- making sure that there's total consistency throughout the company, that I'm surprised that they would be so cavalier with their new acquisitions, the Muppets. Back in the 70's and 80's, there was a main voice for Mickey but he really only did the film stuff. When the parks needed a Mickey voice they just had somebody impersonate it, and it really wasn't that great. I have an old commercial for the electrical parade with the same person doing Mickey, Donald, and Goofy and it's alwful! You can totally tell it's the same guy. It wasn't until the mid 80's that they really reigned that in and made sure that there was 1 Mickey, 1 Donald, 1 Goofy. While I'd love to do this Muppet thing, I think it would be best for Disney to be consistent with the Muppets.
