This is beginning to just come out... I had been wondering about this since everyone I know has been silent on this for the past month.
Also I just talked to my first insider I trust who suggested that Avatar may have been cancelled last month.
Please take that with a grain of salt but they know their stuff......
Heads up Avatar apologists: this thing was put over on the entire Parks/Resorts division with no warning. Almost nobody wants it to succeed.
This @MinnieMGirl knows her stuff, her tweets are about some of the smallest changes in lighting and fixtures, and construction at the parks.
Take this for what you will, but if I could bet right now, I am going to bet this is currently on thin ice, and close to dead.
