Here is an Avatar tidbit from the vacationing Spirit...
The project is technically still active, but is still moving at a snail's pace due to...well, you know.
The bone of contention seems to be the budget. Disney is trying to get it down, but an attraction that JC wants to include would put it over Disney's line in the sand (so to speak).
I'm not gonna go into detail on the ride at the moment, but it appears it would actually be a clone of a ride going in elsewhere, only with a very dense Avatar theme.
