Updated December 17th, 2009: Chuck Season 3 Premiere has been moved up to a January 10th air date. Chuck has been renewed by NBC for a third season. It will start in March 2010, 11 months after the end of season 2. The date is somewhat due to the 2010 Olympics being in the preceding weeks. Because of the late start date, NBC has only ordered 13 episodes.
Season 3 of Chuck is currently available on iTunes for $50 in HD or $35 in normal definition.
