Nahh, Halo is the reason why many people buy Xbox in the first place... Its basically Microsoft's Mario... Halo 4 sold 8.93 million and that was very late in the console cycle vs 7.26 million for uncharted 3.. A new Halo in the next gen console will sell like hot cakes and I think it has a more attach rate than uncharted does (for better or for worse)
