From Comicbookmovie.com and Comic Book Resources information from DC and Warner Brothers are coming from Geoff Johns panel at the New York Comic Con. The highlights included that with the end of the Harry Potter movies Warner Brothers will be filling the void with two comic book movies a year.
With the releases of Green Lantern next year, and Batman 3 and the reboot of Superman in 2012, there hasn't been much news in the way of anything else confirmed. There has been rumors of a Flash movie, as well as a Wonder Woman movie, but one movie that, as of now, is not in the plans,is a Justice League movie. From Geoff Johns, "I'm going to speak frankly: I think our characters are bigger than Marvel's." He said that he'd rather spend time building each character on his or her own rather than "smashing them together."
