I think judging by the trailer that they're going to go with a little more open world anarchy-themed setting. ;/ They're probably doing it to give themselves as developers and Batman a little more freedom. Toss in a few more gadgets including innovative ways to use them, (like the grappling hook in Just Cause 2; awesomeness, anyone?) new finisher moves and another badass engrossing story then we'll have a huge winner on our hands. ;o Rocksteady made Batman shwicked awesome in gaming form with AA like he has been in every other medium for years, I hope they can do it again.
