Yes.
The project isn't "dead" by definition. But it has slowed to a complete crawl, or a stop, depending on who you talk to. It has not been cancelled out right. But there are MAJOR issues holding it back. Nothing should be taken from what Iger said yesterday, according to sources. It was a non-committal response to a Q&A question.
Also, there's a possibility that Avatar won't end up in DAK. As someone put it yesterday "Avatar has a good a chance at ending up in Shanghai, Hong Kong, and DHS as it does in DAK right not. It's up in the air."
But Iger pulling a 2015 time frame from his butt and saying he saw concepts the other day is moot. Is it being worked on? Yes. But it's not an all systems go, let's get this done by 2015 situation. It's a "have a team fiddle around with it and let's see where it goes" situation.
