Will batman knightfall be reprinted for dark knight rises?

Anything is possible. Even though Bane is a villain in The Dark Knight Rises, it's yet to be confirmed that he'd be the only one or that the story would follow the character's arc in Knightfall in any way. I would think it'd be more likely we'd either see new one-shot books spotlighting the characters featured in the films (Bane, Catwoman, etc.), or there would be a trade paperback reprinting key one-or-two-issue appearances by those characters.
