I'd prefer to see Bane as the next big villain, with either Catwoman or Riddler as the secondary tangent threat/ally if needed. I'd love to see the 'Knightfall' storyline done, but I'm not sure if they could fit it all into one movie or if they'd have to end one movie with Azrael taking up the mantle of the bat, then in the next movie showing Bruce Wayne's comeback to reclaim the mantle and defeat Bane for good. That's what I want to see at least. Just don't know if it's possible to pull off well in movie form. I think the techno-batman vis-a-vi Azrael would look bad@$$ on the big screen.
