i suppose this confession has nothing to do with them wanting to get some publicity because they a tv show on.
Most shows look to publicity such as inteviews with its stars to make sure the viewing public know they're returning. It has been that way for decades. I'm not sure why it should come as a susprise to anyone, nor why they should be singled out.
(There's an interview with Ted Danson in the Metro this morning for instance. Why? because CSI is back on C5 tonight).
