this was pretty much confirmed by someone who was there.
I'm now convinced, from things I've been hearing on here and other places, that there are possibly a few cameos from Batman's rogue gallery, including Hugo Strange and Black-Mask. Both who will play minor parts during Bane's lock-down of Gotham and Batman may have to rectify these villains by taking them on in a Pagoda style system, where defeats the least powerful, then the next powerful on and on until Bane.
But again, With this newest bout of information being proven true (I was convinced that it was a fanboy rumor when I heard about it about 3 weeks ago and threw it away) I know absolutely nothing in this film in terms of any context at all.
