FROM WIKIPEDIA:
Season 7
Bill Lawrence told Mike Ausiello at TVGuide.com that Scrubs will return for a "seventh and final season, either on NBC or ABC." He also told Ausiello that if Zach Braff is not interested in doing a seventh and final season, there simply will not be a seventh season. He does, however, feel that Braff will likely stay for a final season.[9] On January 17, 2007, Zach Braff posted on his blog that he would be willing to return to Scrubs for a seventh season if "all the right pieces fall into place", including "Bill Lawrence staying on as creator/head writer" and "some scheduling tweaks."[10] On March 7, 2007, there were reports that, if Braff signed on for another season, he would receive $350,000 an episode, making him one of the highest-paid male TV personalities[11], although Braff claims these reports "have not been very accurate".[12] On March 31, 2007, Braff announced via his blog that he has signed on to a 7th season of Scrubs, if NBC decides to renew it for another season (although Braff has stated that ABC is willing to pick up season 7 if NBC declines).[12]
