The project continually has been cut in size and scope ... what you probably will get is one giant showbuilding with Soarin Over Pandora, a dining facility, a shop and a bit of eye candy. That's it.
That seems like it could be good... for Disney's Hollywood Studios - you would hope that for Disney's Animal Kingdom it would be a bit more substantial than that!
