RockBandRocker has been banned?! Oh well, keep fighting the fight, wherever you are, dude.
I can see why HMX has been elusive about Muse though. If they reveal that Muse is a straight-up DLC possibility, then people will just be wee-wooing until it's released. If HMX straight up denies Muse, then people may stray away from HMX DLC. I too am eagerly awaiting Muse DLC, but I'll have to keep my expectation realistic.
