Avatar 2 and The Return of Avatar

There will be a sequel to the massively successful Avatar and honestly, is anyone out there surprised? According to inmovies.ca, director James Cameron will be focusing on creating a different environment for viewers:

I'm going to be focusing on the ocean on Pandora, which will be equally rich and diverse and crazy and imaginative, but it just won't be a rain forest.

-Cameron

The article also states that Avatar will be returning to theatres in late summer, likely August 2010, and likely in Imax (no word if it'll be Imax 3D but that's probably a given). So if you want more of the Na'vi and seeing it on blu-ray/dvd isn't enough; you'll get your chance to see it again on the big big screen this summer. No word on the title or projected release date of Avatar 2.
