[Nolanverse] It's been 5 years since John Blake became the new Batman. What's been happening in Gotham during that time?

Gotham becomes a national tragedy and is rebuilt using federal, state, and Wayne estate dollars.  The new Batman gets to hone his craft on the small crime that proliferates during the rebuilding process.  He also gets to take advantage of adjustments made to the city infrastructure during the rebuilding that aid the Dark Knight, like personal rapid transit tunnels and equipment caches.

If Gordon's right about the effects of Batman's presence, though, then the criminal element doesn't stop trying to counter Batman.  The Rogue's Gallery continues to populate under the new Batman in the new Gotham.  A new status quo emerges of Batman spending night after night tracking down the latest weirdo to escape from the asylum.
