So that's the title of the third Batman film: The Dark Knight Rises.

So much for The Dark Knight Returns - clearly a better title. Nolan confirmed the sequel's name to the LA Times, also ruling out The Riddler as a villain. He also spoke about his determined dislike of 3D, and had this to add:

"We’ll use many of the same characters as we have all along, and we’ll be introducing some new ones". It's enigmatic as usual, but I'll forgive any director who not only makes Inception but also prefers IMAX to 3D.
