Brain over at the Blue Tights forums was lucky enough to bump into Mike Dougherty, screen­writer for Man of Steel. This is what he had to say,

I asked him if he was a part of the sequel because every­thing I have seen says Singer and Har­ris are writ­ing the script and that he isn’t men­tioned. He con­firmed that he is writ­ing it with the two just like the last pic­ture. I then expressed to him that I was hop­ing the delays of Super­man: The Man of Steel weren’t true. He said that they were on track and that the goal is still to have the movie out in the Sum­mer of 2009. He seemed a lit­tle hes­i­tant about it but did his best to try and reas­sure that it will get done by then. I asked if he could give any more info on the film. He responded, “There are TWO vil­lains,” and he smiled.
