Things are currently looking pretty bad for Bruce and DC seems to indicate that the character doesn't have long to live. He might come back or survive, but I think we are looking at a Tim Drake Batman, particularly because of something I read in one of the Teen Titans TPBs from a little while back. October's going to be crazy:

And come on, it's Grant Morrison. I trust him too much for him to pull a Death of Superman type cop-out.
