Ever since Christopher Nolan finished The Dark Knight, speculation has lingered over whether he will return for a third installment. Batman-on-Film reports that there is "scuttlebutt" that Warner Bros. may be finalizing their plans on Batman 3 in January of next year. Whether or not their announcement will include Nolan is unknown, but it appears that Warners wants kick off the year by clearing up the mystery over who will be directing the movie.
As the site points out, this may work in Nolan's favor, since it would quiet down the speculation about Nolan's participation in Batman 3 before he begins to do press for his upcoming feature Inception. However, the source providing the story also claims that Warner Bros. is planning to make the sequel with or without Nolan.
