I want all the things; future, past, live-action, animated DTV's, give me everything.
When you think about it, Prey's working title of "Skulls" didn't really have anything to do with the movie. It was more of a ref. to the franchise as a whole. "Badlands" though seems a little more specific, so maybe there could be some sort of wasteland aspect to it. I don't necessarily think they'll go as far as Mad Max but something almost like Judge Dredd might not be completely out of the question. Or they could very well be on another planet with a wasteland-type theme to it.
