I think I would be surprised if Hall didn't try to expand its footprint here, and build upon the huge success of 98.1.
Buckley might be another good fit for this market. If I'm not mistaken, they already have quite a presence in Connecticut.
Salem? 790 and 920 would make a really useful duopoly for them.
And, last (and probably least... ;D...I'm sticking to my prediction that one or both of the Cumbre/ADD Radio Group duo of 990 and 1320 will get sold off. For example, I could easily imagine Beasley making use of one of these to expand the reach of its Boston market 1330 signal.
This could be a fascinating time here in good-ole Arbitron 39.
