So, until they rock out their "final" tour and then go back into the studio to make another album and tour again, I'll hold them to it, that this is it. Makes me sad, but at the same time, they've had a hell of a run and if they are quitting on their own terms, then I raise my glass in salute of one of the greatest bands all time!
I second that, they are among the most innovative metal bands of all time.
