What about the Monster's Inc ride? It looks like Buzz Lightyear!
I hope Disney WOrld gets a Disneysea. It would be a great asset, though a bit of a copy of IOA I imagine.
My interpretation of the concept art is that the Toy Story and Monsters Inc images are scenes from the same ride. The Pixar Midway Mania ride, as I understand it, would include scene from each Pixar film. (Though I have heard Cars pitched as another, outside track ride attraction as well. That is what I believe that art image refers.)
As for the new park, my guess would be a second gate in Hong Kong. That's the only Disney installation with only one park now, and it seems to need a second gate to achieve any critical mass in attracting out-of-market tourists. I cannot imagine another Disney theme park in the U.S. for quite some time.
