Could there be a Watchmen 2?

I'm sure the Hollywood studios would think so, but those who have read the book probably have a different idea. The main argument against a Watchmen 2 (imo), is Alan Moore apparently has no plans to return to the material. Without the brain of Mr. Moore behind it, it would likely fail. Also, Moore planned Watchmen out as self-contained piece. It's pretty obvious that a sequel was never part of the master plan, and there isn't quite enough material to make a prequel that interesting. I have run into some people that think a Watchmen 2 could be made and like I said, Hollywood would if they saw money in it. What do you think, would it be worth it? Would you go see a Watchmen 2 in the theaters?
