If I'm reading it correctly, it looks like Phil and Furthur aren't planning to stop touring anytime soon:

Phil Lesh and Bob Weir are in their fourth year of touring with their latest post-Grateful Dead aggregate, Furthur. And as far as Lesh is concerned, the road is where Furthur belongs. . .
"It's been a very interesting development," he notes. "It's to the point where we can play pretty smoothly together. Basically it started because Bob and I realized how much we enjoy playing together; we figured why don't we just play together if it's that much fun. We pulled these guys in and started playing, and it seems to have worked out. I'm enjoying it. It's always an adventure. It's not like I have to worry about it becoming boring; I never know what's going to happen, and that's what I live for, anyway."

GW: This is the longest running post-Grateful Dead collaboration. Is it an ongoing band?
WEIR: Oh yeah. I’m not sure we’re going to do four tours a year. Next year we might do three because we don’t want to run ourselves out of gas. But what I’m here to do is play and I think Phil feels that way as well. And we’re really happy with this band we’ve got together here.
