It's probably better that Pixar is working on it...rather than the Disney people. It was there project. My son will be thrilled. He is wearing down my Toy Story 2 dvd. :D
Well the only good thing about animated movies...You don't have to worry about the actors getting too old to do the roles. (cough*Rocky*cough*Indy*cough) :D
Normally, I don't like the cheapy sequels Disney does for their big movies. But, I wouldn't have minded another Toy Story as long as they got the original people to do it (both cast & production). My 3 year old son just "discovered" Toy Story. And loves Buzz.
