Re: Batman should die in the next film!
It really doesn't matter if Bruce/Batman dies, whatever they do, just make it good. Make it make sense, and tell a great story either way. I can see him dying making a huge impact and if done right really making it have some weight to it. It doesn't have to be done to make a great ending though. However, there's not gonna be many times as fitting as this to do it and make it work in the stories favor.
I think part of the mystique and intrigue to this movie, is you don't know if he will die or not. The fact that Bane is the one to be able to do it, definitely adds to that possibility. Should be a fun ride.
