it could be quite possible that the xbox360 might be at a saturation point. The people who buy games like GTA4 and Halo 3 would probably be the same ones who bought GTA3 and Halo2, and those people might already own Xbox360's. How many people who are *new* to videogames would geek out over GTA4 or Halo3? Probably a number, but it probably doesn't compare to the number of people who have played through the prequels.
