I was going to call BS on this, but went to two sites that I trust - IGN and Batman on Film before I did so, and they both confirm it. Since it's been confirmed, I have to say that many of the more popular titles - Gotham City, The Batman, etc. - really don't fit the theme of the film as promised/teased by the ending of The Dark Knight, whereas this title, even though it's a bit more pedestrian and formulaic than either of the two previous titles, doesn't have that drawback.
Not using The Riddler as the villain - which is what many were expecting - does offset the selection of a rather pedestrian title, so i'm fine with it. In fact, I wouldn't be surprised at this point if Nolan and Co. select as a villain someone we - as an audience - aren't expecting. It would be great to see them once again tackle one of Batman's more obscure, lesser-known villains the way that they did with Batman Begins and the inclusion of Ras al Ghul.
