Latino Review is reporting that Warner Bros. has approached Christopher Nolan to take over everything related to their DC Comics properties. They allege that Nolan will be involved in the development and will produce all of the DC superheroes. They also say they are working toward having Christian Bale reprise his role as Bruce Wayne from The Dark Knight series to join up with Henry Cavill in the Justice League film and that Man of Steel director Zack Snyder will also produce and may direct the project.
Take this with a grain of salt, however, as there has been no confirmation from the studio or anyone else that any of this is true.
Justice League is currently targeted for a 2015 release. Man of Steel will fly into theaters on June 14.
