I don't think it's "right" for Disney to "steal" Pixar's characters and story. Sure, they have the right to do this although it's p***ing Steve Jobs off even more. I ask myself, "What are the creators of Toy Story - AND Nemo AND Monsters Inc - thinking?"
Disney hasn't had the best track record in animation story recently - 2D or 3D (no, it makes no difference. A 3-D film would flop if it were the same poor story). That being said, I don't put full confidence in Disney creating this story. Would this hurt the Toy Story films even more? Obviously, this is another attempt to exploit the characters and pull in the cash.
Plus, this is a slap in the face to today's "Disney story tellers" - the folks at Pixar.
But we'll see how they do. If it takes Pixar to split from Disney, staying successful at creating original stories, then I say, "If you can't join em, beat 'em." As Jim Hill pointed out, maybe Disney would finally get the hit once they have the "True Disney" out there competing.
Plus, Toy Story 3 is already tainted. It's "fake" in my book, and perhaps the animation and story will show that to the rest of the market. . .
Heck, I probably won't watch it (I definitely won't buy it) out of protest. Sounds harsh, but I don't like what they're doing at all.
