Rosita's voice

[Frogpuppeteer]

That's what I said in the second part. It's true. Age does terrible things to a person's voice (though, arguably, Earhta Kitt sounded better the older she got).

the same can be said for Peter Cullen and Optimus Prime

listen to the G1 Voice and the Current movie or Transformers Prime Voice

I thought that was an interesting theory about Cullen since he's also the voice of Eeyore on 'Winnie-the-Pooh,' but someone else is doing the voice for the upcoming movie. The same is true with a lot of characters. I guess Disney is aware of this concept and is trying out some new VAs, sort of like what they did with the Kismit the Toad thing.
