@apujanata, I believe you might be talking about 8.1 Million shipped (SOLD TO RETAIL) article, like this one, which is quite different than sold to customer, which is what simEx track, and therefore it is much more accurate to use NPD's figure, not publisher's figure (which is always shipped, or sold to retail).
@spot-on, I didn't remember seeing 1 Million+ sold in 2008 article. Maybe you can post the URL ? I also didn't remember 8.1 Million sold as of Jan 7 2008 article. All that we have is 4.82 Million sold in US courtesy of NPD data. Do you have URL for article that mentioned 8.1 Million sold in 2007 ?
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.)
