Although this year will be the first without "Community" creator Dan Harmon, the cast told Zap2it at Comic-Con that they're confident their comedy is in good hands with new showrunners David Guarascio and Moses Port.

Says Joel McHale, who worked with them on an NBC pilot in 2007, "They're great, and a lot of the writers are back. It's one of those things where you just kind of proceed. We're not back to work, so I'm not sure how it all goes yet. I'm excited that we got the pickup and that we're on TV. Thank God!"
