Michael Uslan is officially the only person signed on for the next Batman movie, though many are confident that Bale and Nolan will return. So the first bit of official news comes from the only guy with a contract a la Bat. The plan is to have Batman sequel out in 2011:

Uslan will be onboard as executive producer for the "Dark Knight" sequel, which he estimates will be theaters by 2011. As for the identity of the next round of Batman's supervillains and love interests, Uslan remains tight-lipped. "It's one of those deals where if I told you, I'd have to kill you," he says with a chuckle.
