Superman: Man of Steel

Latino Review got an exclusive talk with Paul Levitz, the President of DC Comics.
When asked about Superman: Man of Steel, Paul had this to say.

“Everyone is waiting for Nolan to sign on for another Batman, once that happens, the release date for Superman and all other future projects will follow.”

And there is more. DC wants Brandon Routh, Superman from Superman Returns, to return as the Son of Krypton.
So it won't be a full reboot if it has the same actor.
DC is waiting for Chris Nolan to sign the deal with the next Batman, and DC wants him to commit to a July 2011 release. If that happens then the following superhero films will be released.

Green Lantern Summer 2010
Batman 3 Summer 2011
New Superman reboot Summer 2012
Also in the mix is The Flash.

Green Lantern will come out before Superman, but what if Brandon Routh did a cameo in the Green Lantern film as Clark Kent (as a recent rumor I heard said might happen)? Would DC be trying to copy Marvel in the wake of the Avengers to create, *gasp*, the Justice League?
