This is great news. I was more than certain that the show was getting axed, especially with the American Dad renewal. With a short order (no pun intended) of 13 episodes, I'd expect to see this come back next Spring, once they're run through the gamut of AD/Cleveland episodes early in the fall.
If you got turned off by the admittedly-awful first episode, give it another chance. You won't be sorry.
I'm not sure how to link this... so click on this link Arrested Development Season 2 (The W at Amazon) and then click "Read More". The ad is at the bottom of the page that comes up. If you don't already have them both, it's a steal.
