Cameron and Disney Imagineers unveiled some concept art along with an explanation of the new land.
This is one of the most ridiculous things I have ever heard. First off, I didn't even know Disney had rights to Avatar. This is something I would expect from Universal Studios, not Disney. However, this will add a lot of stock in the attraction sparse Animal Kingdom park. Avatar Land will join Expedition Everest, Kilimanjaro Safaris, Kali River Rapids, and Dinosaur.
