Funny how this pops up earlier today/last night, as I went to bed with some PT playing on my iPod/iHome next to my bed. I had put on my expanded tracklist of In Absentia, easily one of my favorites of theirs, B-Sides included.
It's definitely sad to hear that from SW, but as prog does, he must move forward, and the others have all slowly found their own projects since 2009, so it's not like they were forced to sit and wait for SW before moving on to other things.
I wonder if SW will ever release other PT-related albums, like old live albums or outtakes, or perhaps re-issues with proper bonus tracks, such as studio-sessions, B-Sides, alternate takes, etc. etc. It'd be neat to see him release his own past works in the same way his King Crimson re-issues have been handled. Then again, I kind of hope not because I'm pretty poor as it is...
