When writers deals were made for 30 Rock for next fall, they were were made with the presumption that the upcoming 13-episode seventh season will be the Emmy-winning comedy’s swan song. But during today’s NBC conference call the network’s chairman Bob Greenblatt said that there no decision has been made to end 30 Rock, The Office or Community after the upcoming season. “We haven’t definitively said that on anything yet,” he said. Like 30 Rock, Community was picked up for 13 episodes and is being moved to the Friday 8 PM slot where NBC sent Chuck for its final 13-episode season last fall. The Office was renewed for 22 episodes. Asked whether Community creator Dan Harmon will return as showrunner next season, Greenblatt said, “I expect his voice to be part of it,” adding that it is still unclear if that will be in his current role or as a consultant. Greenblatt dismissed the notion that the discussion about Harmon possibly stepping down from day-to-day oversight of the show stems from his ongoing feud with co-star Chevy Chase, saying that there are larger factors beyond that.
