That's the good news. Here's the bad news: The 13-episode pickup came after Warner Bros. agreed to make significant budget concessions, including scaling back the number of episodes several members of the show's stellar supporting cast will appear in and, per one insider, possibly eliminating one actor altogether (R.I.P. Anna Wu?). The show is also expected to cut two of its staff writers.
This does not bode well for this great show. It's all the supporting actors that make it as funny as it is. Sounds to me like they put the death knell on it anyway.
