According to an interview Wizard posted with Dan DiDio one question touched on all the rumors....
Online rumors already say Batman is going to die—but come on, you’re DC…you wouldn’t kill Bruce, would you?
"I’m not sure where these rumors started from, and I’m not sure what people are talking about there, but we do have a rather exciting series, a big storyline starting within Batman and being written with Grant Morrison called “Batman: R.I.P.” I don’t know if that adds to the confusion or creates answers, but it’s a big story that only Grant can tell. And since Grant is doing Final Crisis and Batman, it’s hard for me to say what the next steps may be."
So what could that possibly mean...could there be a grain of truth in all this Death of Batman talk after all??
