From Variety today:
It was a good weekend for big stars and underdogs as ABC, Fox and the WB all moved one step closer to setting their fall skeds.
Three webs all but wrapped up their series orders for the 2005-06 season, with new Fox Entertainment topper Peter Liguori moving with particular speed, picking up much of his first crop of shows nearly a week before the net's Thursday upfront presentation.
News was particularly good for many (but not all) skeins that had been hanging by a thread.
Fox told 20th Century Fox and Imagine TV that "Arrested Development" will be back for another season, while "The Bernie Mac Show" also got a surprise renewal.
Futon Critic confirms the renewal. Apparently, Liguori's plan was to order two seasons in order to keep the licensing fee down. Ultimately he went with a single season.
