Oh one other thing, not important but in my head I can totally connect the end of TDKR to this Batman to pretend it's all in the same universe.
Bruce clearly states to Alfred after 20 years of fighting bad guys, good guys dying and how many are left making it clear just how long he's been doing this. I can totally see things falling out with Catwoman or she dies by the hands of somebody (maybe Hush), while "Robin" Blake :x is being a vigilante in Gotham. Bruce is forced to return to being Batman, Blake dies, more villains pop up, Joker returns makes a Harley, etc.
It can all fit
