Disney's new themed area Pandora-The World of Avatar has an animatronic Na'vi (previously at Neatorama). You can see the technology has come a long way since the Hall of Presidents was launched. Check out this Shaman, recorded during a publicity preview run.
The the Na’vi River Journey is one of two new Avatar-themed rides. The Shaman of Songs you see here is the climax, and the only animatronic. From Inside the Magic:
Up to this point in the attraction, all of the creatures you have encountered (including the Na’vi) have actually been presented on layers of screens that are positioned inside beautiful sets. The sights are impressive, but they are projections nonetheless. In the attraction’s final scene, though, we are treated to a rather climatic encounter. Sitting and singing, the Shaman of Songs is the most fantastic animatronic on Walt Disney World property to date.
The ride officially opens to the public May 27. -via Gizmodo
