This article basically explains everything. We can watch Arrested Development reruns either on MSN's video service (they had one?), HDNet (for you home theater enthusiasts), and G4 (another non gaming, girls, gadgets, 4th g related show they have added to their lineup).
At least this show will get more exposure. There is buzz about a movie, which Will Arnett commented on in a recent interview. It will never happen, but news like this helps keep the dream alive.
