Nikki Finke’s Deadline has a so-called “speculative” schedule for NBC’s fall season, in the run-up to the network’s upfront presentation on Monday. Included are 30 Rock, which is said to be moving to Wednesday night along with Parks and Recreation, and Smash, moving to Thursdays. Missing? Rock Center, the Brian Williams newsmagazine. This doesn’t necessarily mean the end for the low-rated series–the schedule is anything but definitive, and even if it is, Rock Center has a way of cropping up. The series came on air earlier than planned after last fall’s Playboy Club flopped.
