Speaking to investors, Warner Bros. chairman and CEO Barry Meyer revealed that they were "nearing" a greenlight on The Flash.  According to Heat Vision, Meyer also spoke about their other superhero properties.  He repeated that Christopher Nolan's Batman 3 was set for July 20, 2012 and that the new Superman movie—produced by Nolan and written by David Goyer (Batman Begins) and rumored to be titled The Man of Steel—was scheduled for the 2012 holiday season.

Meyer also revealed that the studio was had films for Wonder Woman, Aquaman, and Mad Magazine characters in development.  Hit the jump for what we know about all of these projects, including Steve's interview with rumored Flash director Greg Berlanti (Life as We Know It).

We know next to nothing on Batman 3.  Christopher Nolan will direct it and David Goyer is rumored to be writing it with Jonathan Nolan (The Dark Knight).

As for The Flash, we again know very little.  When Steve spoke with Berlanti (who wrote and produced Green Lantern) at Showest, Berlanti was coy and said his focus was currently on other projects.  Warner Bros.' Showest presentation said they're aiming to have the film also hit in 2012.

For those who don't know the character, The Flash's superpower is that he can run really fast and he has a fun rogue's gallery.  There's currently a debate among fans on which Flash alter-ego should be in the movie: Barry Allen or Wally West.  I assume they would go with Allen since he was the first Flash.

Moving on to the other superheroes, we know that former Warner Premiere President Diane Nelson, now head of DC Entertainment was brought on to get the DC superheroes stuck in development hell back to the land of the living.  I would say she's been highly effective.  Nolan came on to "grandfather" a new Superman movie, they've got David Goyer to write it (it's the hiring I find effective, not the actual hire), and Green Lantern will be the first major DC superhero to hit the big screen that isn't Batman or Superman (although production on that film began before her tenure began).

So what of the other major DC superheroes?  It's no surprise that they have Wonder Woman in development.  But Aquaman?  Maybe if it's a comedy.  He's a silly character and that's why people make fun of him.  As for the Mad Magazine characters, I can only speculate/hope that they're talking Spy vs. Spy.
