How do you up attendance at a local superhero film convention? Easy, you have legendary comic book creators Geoff Johns (who worked on this summer's Green Lantern) and Jim Lee announce that they will be dropping a major bombshell while attending the Hero Complex Film Festival on June 11th concerning director Zack Snyder and his upcoming Man of Steel that will effect the entire movie world of the DC Entertainment Universe.

Its anybody's guess as to what big news they hold in their possession. Early speculation is that they will be announcing Justice League of America casting that could include Man of Steel's Henry Cavill, even though Zack Snyder has been adamant that his Superman adventure will not be tied to this DC Comics ensemble. He was also adamant that Zod wouldn't be appearing in the Man of Steel reboot, and we all know how that turned out.
