Should It Just Be Called Batman v. Batman: Dawn of Batman?
The rumor originated from Heroic Hollywood, which reported on a rumor that Warner Bros. have been won over by Ben Affleck's performance to such an extent, that they want more Batman in Batman v. Superman. Ironically, the film was originally intended to be a Man of Steel sequel. As of now, however, a formal Man of Steel sequel has been put on hold, while a Affleck driven solo Batman picture already has a 2017-2018 release window.
Can We Handle That Much Batman?
Logistically, Warner's Bros. rumored attitude makes sense. The Batman license is very hot right now, helping sell video games, comics, and merchandise. Anyone who saw Man of Steel will easily note the influences that The Dark Knight Trilogy had on its overall tone. Ditto with the Suicide Squad, which is slated to have a Batman cameo. Warner Bros. may want to center their DC Movie universe around the very marketable Batman, as Marvel did with Iron Man.
