Bleeding Cool ran a story a few days ago claiming they had a source or something that said that Bane indeed does physically break Batman's back. We saw a shot of Bruce with a cane so we know he is injured. It's possible he has his back broken or whatever and gets tossed in a prison where he has to "rise" to the occasion to recuperate. He has to find the will power to return to face Bane again. I think that old guy in the trailer might be like a mentor he has. I also think we could see Juno Temple's character in that prision. I believe she's supposed to be playing a "street urchin". I'm still convinced that we won't see Bruce be killed off. Crippled yes but not killed. The Eight Year gap is something incredibly interesting that brings a whole lot of possibilities into play.
