I knew this over a year ago. When the stream of Band Hero, Beatles Rock Band, and Guitar Hero # came out and all of them failed to move the charts. The Music Genre tried moving to DJHero and other gimicks (LEGO Rock band) to regain some ground, but that was a flop too and I doubt they'll ever be able to come back like it did before. The expensive plastic incompatible periphreals didn't help either.
