Yeah, I remember that, when Disney thought they were actually anywhere near as good as Pixar. Silly Disney.
However, as Jekyll Juice mentioned about John Lasseter, Disney's animation has a chance again (can't wait for The Princess and The Frog

)
However, what I'm concerned of regarding voices will be Wheezy, the Penguin in Toy Story 2. His voice actor died in 2005 unfortunately, and I was wondering if Pixar was still going to include him as a character in Toy Story 3, as they are doing with Slinky.
But more on the subject of VAs is the returning of Tom Hanks and Tim Allen. Very glad they are returning, because the role would not be the same without them.
And even though 2010 is a long time away, Pixar/Disney are set to re-release Toy Story 1 and Toy Story 2 in Disney Digital 3D before number 3's release.
