I wouldn't look at it that way. Some of the stuff being sold makes perfect sense. The wardrobe cases were probably from the Crimson era when they were much more into aesthetics and now serve no purpose. Dan uses Orange cabs instead of Ampeg these days, so need need for that and the case he had made for it. They have guitar boats, so no need for all the individual instrument cases. The guitars that are up, I haven't seen Matt play in ages, etc.
I'd argue that Alk3 is bigger than they've been in a long time.
