When does season 2 of Game of Thrones begin?

Sunday (9:00 PM - 10:00 PM) 04-01-2012 on HBO will be the first show

It started filming in July from what I heard... and it is a pretty expensive show. It should come out within the new year, I'm not guessing any sooner.

Just a heads up. On April 19, 2011, after airing only one episode, HBO announced that it had renewed Game of Thrones for a second season which will premiere in April 2012. On September 12th, 2011, it was announced that filmmaker Neil Marshall would direct the ninth episode of the second season, depicting the Battle of the Blackwater. This episode will be written by Martin. Other details of the forthcoming second season are not yet available.
