I have to question Halo 2 and the impact it is going to make. I do not forsee it helping Xbox sales much, if any. It\'s a sequel, which means two things. First, people who have the first one and liked it, will buy it. Second, people who don\'t have the first, are most likely not interested in the second.
Then you take in account all the high calibur FPS suppose to come out around the same time as HALO 2.
