When the internet exploded over Ben Affleck being cast as Batman, one thing Warner said about the character is that they wanted an older version of him. That definitely means they wouldn’t be re-hashing the origin yet again, and now Warner has given more information about what most people have suspected.
Deadline has a quote from Warner at a Bank of America conference, and the description sounds a lot like the New 52 Batman:
“kind of tired and weary and seasoned and been doing it for a while,”
In the New 52, Superman is meant to be the world’s first superhero. However by the time Superman comes on the scene, Batman has been operating for a long time in Gotham as something of an urban legend. This was done so that Batman’s long continuity and multiple Robins wouldn’t be wiped out with the reboot, and it sounds like they’re setting the new movies in a similar universe.
