Go back about 30 pages and watch the movie trailer that describes Pandora. This is less about the movie than it is about the planet. I've never seen the movie (although is now on top of my Netflix queue), but I'm still excited for the possibilities. The collaboration of James Cameron and Joe Rohde itself should produce excitement in anyone that hears about this. From the announcement, it sounds to me like the only thing that is inked right now is the contract, so the imagineering is just about to begin.
I'm happy to see Animal Kingdom move away from the zoo theme as well. Although they have done amazing things for/with animals, they have never wanted AK to be just another zoo. Adding Australia or another continent to the park would have been nice, but it would have kept the same zoo theme. This gives them the opportunity to move beyond that. It also has HUGE potential for after dark entertainment that will be able to co-exist with the animals.
BTW - Kudos to Tom Staggs. You clearly intend to make a positive mark on Disney and I can't wait to see what's to come.
