Only FOX would go to the trouble of announcing three different lineups. And only FOX would leave PIS out of all three. Looks like the rumor of a summer return can be discarded for now, unless one of their newest series actually manages to pull worse ratings than PIS did. And even then, they'll probably beg CBS for their own CSI series first.Maybe GSN can get ahold of it. They have to air something after the Mole reruns are used up.
