I wonder why now? Most of us figured it'd happen someday, but it's certainly a dramatic move. Declining ticket sales would certainly seem to be a part of it, but I don't think that the lineup was the problem there. Seemed to me that prices were a bigger factor, and their decision to play venues far, far too big for them (which led to the prices).
I'll got to see damn near any MP project, and this will be no different, but the thing that will really matter is if they go back to playing organic, live concerts again. I stopped going to many of them because I found them boring. MP is the difference maker there.
