I'm not sure when Scrubs will reappear on the schedule with new episodes. The Writer's Guild of America is currently on strike, so when the remainder of the taped shows airs there will be a gap of new Scrubs episodes.
I heard that the creator of the show will not write a cheap wrap-up episode to the season to use as an impromptu series finale because he feels that would be cheating the fans. I agree, wait until the strike is over and then film the rest of the episodes.
As you may well know this strike is affecting not only all scripted television show,s but motion pictures as well.
I hope it will be over soon enough and the writers get what they are asking for.
