I would say if the 52% figure in the above article is true, Halo 3 could hit 15 million or so, at least 10 million, considering the worldwide expectancy on the exchange now is hovering around 60 million, it would not be inconceivable for such a strong flagship title to be owned by 1/4 Xbox 360 owners. Although the market is saturated with FPSs (go with me on this one) most average gamers would buy the flagship, which is Halo. On the original Xbox, I only had Halo and Halo 2 as my FPS games. Those who are attracted to the genre will buy more major releases (i.e. Halos, CoDs, Ghost Recons, Rainbow 6s, etc.) than the average gamer. Now I am more into FPSs, but Halo was still the first I really liked due to smooth control and production values. The saturation comes from (IMO) grade C titles like Timeshift and Frontlines (maybe Frontlines is a B, but whatever, I personally hated the demo.)
