I'm not close to the band or "in the know," but Aresti now lives a few thousand miles away from the rest of the band. And my understanding is that he is focusing more on his "private life" than on being a musician.
Frank lives in the San Francisco area, Ray lives in Phoenix, and Jim at least started in Connecticut. Don't know if he lives there still, and I have no idea where Joey and Bobby live. That said, I don't think where any of them live is of any particular importance. Jim is the primary (and often only) songwriter, and he has said more than once that he basically puts together completed songs and sends files (previously tapes) to everyone else to give input and learn.
I personally would LOVE to have Frank back full time. I generally preferred his songs and solos to Jim's. Although he was only minimally involved in songwriting for DiaDL, I suspect his involvement -- coupled with Ray's greater involvement in writing -- was one of the main reasons why DiaDL was so good. As "goo-goo" mentioned, however, he has a full time job (artist relations with Dunlop, and previously with D'Addario), so any significant future involvement with FW is, sadly, unlikely at best.
