I'm sure it will continue...in fact if you can pick up WAAF 107.3 out of Worcester--sister station of WRKO--you MIGHT be able to hear them there, too next year. WRKO's signal has problems to the west (has to "protect" other signals) and it's been suggested WAAF may be used, at least for night games.
WTIC has a great signal--was able to pick them up in Ohio while visiting a friend (kept up with my Sox that way). I think their antenna is on or near Talcott Mountain (saw the tower while visiting the Heublein Tower--nice views) in
Avon/Salisbury/Farmington area
I live not far from that area. It's actually the Avon/Simsbury/Farmington area, not Salisbury... :o)
