NBC Greenlights "Office" Spinoff

So NBC has finally green-lighted the long-rumored "Office" spinoff. Interesting. All of the rumors that I've seen to date had the spinoff focusing on Dwight, but Rainn Wilson called that "preposterous" in an interview a couple of weeks ago, so who knows...

Maybe a show about the crew at Bob Vance Refrigeration? Maybe Karen is coming back after her other show on Fox crashed and burned? Maybe Kevin's getting his own show about trying to hit it big as a Police cover band?

Edited to add: In other good NBC news, apparently 30 Rock was picked up for a 3rd season.
