considering alot of the DBS stuff on OOA was written throughout Chester's entire life, I doubt we'll see a new album soon. it obviously takes a while for some pieces on an acoustic that you write in your downtime to become fully fledged songs, and it's not something I forsee Chester doing alot of these days, particularly in light of his involvement with STP.
if it ever happens again, it'll take years. and I have a nasty feeling that it won't ever.
I doubt the label would even want to pick up the project again, we all saw how badly promoted the entire thing was, it's clear that someone in those offices isn't remotely interested in letting this band get anywhere...
