Details of the attractions in the creation of the film's Pandora include a big Soarin' style attraction and boat ride of some sort. There's also no official opening date, but we're still at least two years out at a best guess.
What stirred this post was some fantastic new aerials photos that I noticed were posted to Themeparx, showing off current construction of the Avatar land.
A while back some plans for the attractions in the Avatar area were leaked, and it looks like they were spot on. I took one of the aerial images and outlined what seems to match to these plans (image below it) perfectly in yellow. You can clearly see the curved footers that will be needed for the seating mechanisms for the four separate theaters in the Soarin' style ride. The adjacent building, which will have the boat ride pass through, can also be seen.
There's plenty of other structures underway in the area, including footers for what I would think could be the start of floating islands and the facade for the huge show building. Things will be more interesting in the coming months as the structure are finished, and we get a better idea of how this will all come together!
