Deadline article confirming it’s a done deal:
|After several weeks of negotiations, Community producer Sony Pictures TV just confirmed that there are deals in place for series creator/former showrunner Dan Harmon and former co-exec producer Chris McKenna to returning as executive producers for Season 5. The studio is not saying that the 13-season fifth season will be the cult comedy’s final installment, though that’s what I’ve been hearing. Harmon announced his return to the show via Twitter a week ago.|
Andy Bobrow and Tim Saccardo are also coming back.
