I'll echo what I said in the Boston board: while I still miss WFNX, it's great to see Clear Channel do something different with that frequency, and I hope it succeeds.
But no, unfortunately there doesn't seem to be a place for Clear Channel to put this format. Considering how successful KTU is, I don't see them tweaking it back towards pure dance anytime too soon. Z100, Lite FM, and Q104.3 definitely aren't going anywhere, nor should they. That leaves Power 105.1, which I gather is mainly still around in order to keep Hot 97 from dominating the ratings. There's also the question of whether a separate "dance" station would eat too much into KTU's ratings. But then again, CC doesn't seem to be concerned about KTU's effect on Z100's ratings, and KTU really has more in common with Z than it would with an "Evolution" type station.
If anything, I could see this giving CBS an incentive to turn 92.3 Now into a straight-up dance station. They don't have much to lose, ratings-wise. But we'll see what happens.
