I think there's plenty of potential
there for exploring the world further, and expanding the Avatar universe beyond just that one world (it would be fun to see Sully exploring other planets, for instance, or joining a group of alien mercenaries for some kind of mission), but unfortunately it sounds like all Cameron is really
interested in doing is hitting the same conservation theme again and again. And only exploring different corners of Pandora and it's moons.
Which is going to get really old really quick.
