Entertainment Weekly posted an interview with James Cameron two days before the release of Avatar on DVD and Blu-ray.   No extras and no thrills DVD means the next one will have added scenes but no revisons.

Cameron told EW:

“I’m not into revision. I think every film should be exactly as it was executed in the moment. We’re not changing the rest of the film, we’re just dropping these scenes in. I actually don’t believe…like when George went back and put new creatures into the original Star Wars, I find that disturbing. It’s a revision of history. That bothers me. I certainly wouldn’t go back and do that to any of my films. A film I made in 1984, it’s what it is. It’s a creature of its time. But with these new scenes we’re adding, I think people certainly had an appetite for more Avatar than we gave them. Nobody complained about it being too long. The scenes we’re putting back are righteous scenes, they’re not Jake sitting around talking about his childhood.”
