So let's say we are in some sort of alternate reality. Tomorrow DC will decide to have Batman age in real time. Which means he will age and eventually have to retire, die, pass on the cowl, etc...
You can have your pick of established alternate futures for Batman or something completely new.
So how should Batman age, and how should his career end?
Dark Knight Returns? Batman Beyond? Killed in action? A peaceful retirement? Something wild, like John Byrne's Generations where he becomes almost immortal? Something else entirely?
I considered putting up a poll, but there are so many options I didn't bother. Also this is not an argument for Batman aging, retiring or dying. It's just for discussion about IF that happened, how would you like to see it go down.
I'm sure this has been done before, but I haven't seen it and I'd like to hear some thoughts on the subject.
