It is the final Nolan/Bale batman flick, and what better way to go out? Bane broke the Bat, but in this world maybe he kills him and sends him into martyrdom. That would end the series on a dark note, and any later film would be obviously separate.
Will Batman die in Dark Knight Rises?
Well Nolan said this was going to be the end of Batmans story and it will be in a way that no one else can follow it on unless it's a reboot.
Batman dying in a movie...or in a comic....or anything in particular...hmmmm....no. This is a comic book movie set to cater to EVERYONE. The franchise is worth billions to Warner Brother's from its last movie already. Furthermore the rumor mills of the studio has sets to see Batman in a Justice League movie as well within the following year of 2013 or 2014. But not with Bale assumingly. I'll believe Warner Brothers or DC Comics would kill off a billion dollar character like Batman than I would check my window for flying pigs.
