I just saw the other day that they've started production on the fourth season of Arrested Development. There will be 10 episodes, available on Netflix, and they'll be used to segue into the Arrested Development movie coming next year for those of you that have missed that news.
I didn't really watch the show when it was on Fox, but I've since fallen in love with the show. I think the writing was its own worst enemy, as the self-replicating humor probably didn't catch on with casual viewers that missed previous episodes.
I'm very excited this is becoming a reality.
