Hence why it's a pie in the sky hope.
Not necessarily. An L.A.Times article today stated that NBC was at this time undecided as to the futures of two of it's Thursday sit coms with young skewing, passionate followings; Parks and Recs and Community. The article acknowleges the 2 shows ratings challenges.
I had a feeling NBC wasn't completly sold on the show's demise. Why fire the showrunner on a show you know
is getting only one final season? But to be honest, they might also have been worried about legal trouble from Chase if Harmon had returned.
To have Community come back at this point would be even more satisfying ("most" satisfying, would be Harmon's unlikly return) because Chevy would be gone. There is at least some hope.
