Could James Cameron's ego finally be getting the best of him? JoBlo just ran a piece of an interview in which Cameron says he will only make Avatar movies from here on out:

Last year I basically completely disbanded my production company’s development arm. So I’m not interested in developing anything. I’m in the “Avatar” business. Period. That’s it. I’m making “Avatar 2,” “Avatar 3,” maybe “Avatar 4,” and I’m not going to produce other people’s movies for them. I’m not interested in taking scripts. And that all sounds I suppose a little bit restricted, but the point is I think within the “Avatar” landscape I can say everything I need to say that I think needs to be said, in terms of the state of the world and what I think we need to be doing about it. And doing it in an entertaining way.

Okay, I get it: Biggest movie of all time. Sure. But, Jesus, the moviegoing public is going to get tired of the Avatar universe sooner or later, aren't they?
