An extened Avatar to be released to theatres in the Fall?

Cameron said,

The wildcard is that we might be re-releasing the movie this fall. It's kind of gotten stomped out (in theaters) because of Alice in Wonderland. The word we're getting back from exhibitors is we probably left a couple of hundred million dollars on the table as a result. The question is the appetite still going to be there after the summer glut of movies. We're going to assess that. We're talking about maybe adding in additional footage and doing something creative.

Slashfilm speculates that there could be up to 20 minutes of new footage available for the expanded Avatar, since Cameron has said he has five or six minutes of deleted scenes with finished effects, and another 15 minutes for which the effects were never completed — but they could be, if there was money to be made.
