Most stations will flip this year.... a couple will survive.... probably the Wave, perhaps Chicago, Detroit, Philadelphia (which sort of came back after a flip).
I don't see the future as smooth.... yes, there are a great many people (I call them "smoothies") who are comfortable with it and they think it includes Luther Vandross, Sade and Anita Baker hits from 20 years ago. They don't have a clue as to how smooth jazz was born, what it represented to us in the late 80's and early 90's - and quite honestly, they don't care. Smooth jazz is the only outlet for music from yesterday that they can identify with. Corporate radio has essentially shut them out in favor of today's flavor of the month.
I see the future as being a hybrid of fusion, jazz, funk and rock elements. This music will be available on satellite, HD, internet and indie sources. Distribution will be digital download - and if you go to a show, perhaps you can get an actual CD.
I don't see the future as being revamped hits of yesterday. While the ""smoothies" may love it, the rest of us who aren't ready to become horizontal (nod to Cabbage!

) - well, we want music which interests us and motivates us - and not necessarily because we want to sit back, relax and live a "lifestyle" pushed upon us by advertisers and market-meisters.
These days, I see the collapse of smooth jazz radio as being a good thing. Because musicians and artists no longer will have to adhere to constraints and formats - and will hopefully focus on great music and melodies - rather than getting a spot in the rotation on corporate radio stations.
