Another factor for FPS vs music games is that FPS' are FAR more popular than music games ever were. COD sells over 10m copies every year, so even if a large number of people say 'I don't want to buy this anymore', the game will probably still sell millions and draw huge revenue. And even if COD miraculously slumps, there's always Halo, Gears of War, and on a smaller scale Medal of Honour (along with the dozens of other FPS's that get released every year) for the genre to fall back on.
