As others have said, typically a pre-parade or meet & greet is what a new animated movie gets when it is first released. The exception recently is The Princess and the Frog, which got a meet & greet, the Showboat Jubilee, and a
welcome ceremony.
Apparently at the
D23 Expo in September, Disney had meet & greets with characters from the upcoming version of Alice in Wonderland. If they would take the time to have the characters there, I would
think that they would put the characters in the parks . . .
maybe(?). That's just what I would conclude (very indefinitely). I'm not sure how that would work out with the versions of the characters that are already at WDW from the animated version, though. Hmmm.
But there's still time if they were to do something, though. The characters from Up came to Hollywood Studios two weeks before the movie's release, and there's still a month left until Alice's release.
And as for Toy Story 3, I would expect a meet & greet with one/some of the new characters . . . perhaps.
