So it looks like they're actually still filming! I just found this online (it contains very minor spoilers) with the cast talking about things happening when the show comes back in the spring!
Yeah, so even if the worst happened and NBC didn't air them, they'll still see the light of day. Parks and Rec was pulled and returned with a vengeance, so I don't believe all hope is dead.
I'm glad 30 Rock is coming back and I don't begrudge Up All Night getting moved to Thursdays, but christ. Whitney is still rotten and every commercial I've seen of Are You There, Chelsea makes it look just execrable.
