it's a moo point

I don't think they won't air what's already been filmed, because that's money. And they ordered a full season and it would kind of cruel to not stick to that. The problem is when it's going to air. If NBC ends up putting comedies on another night and puts P&R there, it's almost definitely going to fail, which means S3 will probably end up being the last. It's better that we get the third season than none at all, I guess, but still.
