Warren Haynes and Derek Trucks exit ABB

....just read where Waren Haynes and Derek Trucks will be leaving the Alllman Brothers Band at the end of this year. I have enjoyed watching Warren through the years but I was never much of a Derek Trucks fan who by the way is a fantastic guitar player - I just never cared for his style of play. I am a big Dickey Betts fan but do not see him coming back although I would really like to see it as there is some bad blood between him and Gregg. After 45 years I wonder what is going to happen to this band ???? Gregg, Jaimoe and Butch and still can play pretty good.
