Wasn't the most recent iteration of Watchmen a new generation of previous heroes (some new, some old)? I would imagine it would be the same here. Dr. Manhattan is probably on Mars. Maybe we'll have a Nite Owl or Silk Spectre III, and with Ozymandis serving in some sort of Illuminati manner. Of course, Rorshach's journal was released, so it'll be interesting to see if that is referenced/comes in to play at all. Regardless, I'm excited for what this might become, especially on HBO.
