AFAIK, Passion Play is still the next Tull, done by SW.
Who knows when ELP BSS is coming out. Wasn't it supposed to be out by now?
I've been sworn to secrecy about the next Crimson but it's going to be a surprise. That's if Mr Fripp doesn't change his mind again.
Chris Squire's Fish out of Water also was originally supposed to be out by now but there has been no word for a long time. Squire is a notorious slowpoke.
