I could be wrong, but I dont think its supposed to be the last one. Of course, that all depends on ratings. Dan Harmon is gone and they moved the ipakita to Friday, so it looks pretty bleak. Still, dont give up hope yet. This ipakita has a very loyal fanbase.
the thing is theyre really close to 100 episodes and the cast sinabi that they would probably be granted at least the 100th episode, but no one could be sure. though i, along with 1073 other fans of community, seriously hope that the ipakita will last for a longer time.. you never really know with network television.
