IF WABC is sold, the retention of the call letters would be negotiated between the two parties. Since the call letters have a great deal of equity with the listeners, a new owner would probably want to retain them and if ABC required a call letter changee in the deal, the property would probably be worth less than if the call letters came with it.
If the call letters were retained they would remain WABC. There is no hyphen-am calls on the AM band. The TV station would remain WABC-TV and there could also be a WABC-FM, should ABC allow it, in any market east of the Mississippi regardless of the station's ownership.
If the call letters were to change, yes, there is prescedence for three letter calls being re-granted to their heritage frequencies. This happened when the WHN calls returned to 1050 in the '60's (after a long stint as WMGM) and has happened on numerous other occasions, among them KHJ LA, KRE Berkeley, KYW Philadelphia, WHK and WJW Cleveland to name a few.
The new owners would have to get permission from CBS to become WJZ. Those call letters are currently in use by their Baltimore TV station.
It might take some jockeying and call-letter parking and moving, but it is possible (although not probable) that the WHN call letters could end up on 770, since ABC also owns the facility that once had those calls.
