Sad day for Prog Rock/Metal fans

That is a bummer. But maybe it'll mean more Liquid Tension albums. I would honestly be very surprised if Portnoy and Petrucci stopped working together, since Portnoy Brought Petrucci in (on his wife's suggestion, I believe) on LTE.

I'm sure all the guys will keep on makin music, and I'm sure it'll all be good. Probably quite different, though.
