I stumbled across this article on batwatch.net and don't think I've seen anyone mention in on CV:
Apparently, there have been rumors of a TV series centered around the GCPD in a similar vein to Greg Rucka's Gotham Central. Seems like a pretty cool idea, in my opinion. I don't think the idea of it being set in The Dark Knight trilogy's universe. But so long as the prospective show is good I would be more than willing to look past that.
