I was actually just coming to post about this as well. I think it's the right time. The last season, while I still enjoyed it, seemed to have more misses than hits as far as episodes. Most of the major loose ends in the series have basically been wrapped up already (Michael leaving, Jim and Pam's growth as a family, Andy taking over and getting together with Erin, etc). I really hope Steve Carrell makes some sort of cameo this season. Was kind of surprised we didn't get a "What's Michael up to?" episode this past year. Don't forget that there's supposed to be a Dwight spinoff at some point (apparently called "The Farm"), so the characters might not all be going away completely.
