There won't likely be any formal announcements, but combing through the advance listings The Futon Critic saw that ABC was doubling up on Better Off Ted and Scrubs airings in January on a schedule that will have the 13 episodes orders of both shows completed by the end of the month (including special Friday January 1 episodes - two for BOT and one for Scrubs). Starting Tuesday January 5, ABC will air Scrubs at 8pm and 9pm and BOT at 8:30p and 9:30p for the remainder of the month.
Many (including us) have wondered why ABC ever brought Better Off Ted back in the first place based on the ratings (no opinion on show quality) last season. At least with Scrubs there were additional episodes for syndication.
Though it won't likely quiet speculation from fans, this seems to significantly reduce (all the way down to zero) the likelihood that either show will get renewed for additional episodes.
