I have a question, didn't Gears of War, Bioshock & Lost Planet and a few other big FPS games already draw in most of the Halo crowd?
As far as Metroids boost(it was mention in this post so I'm gonna comment) I think it'll see a big first week. nothing massive, the first one actually sold well and people are pretty excited for the third. I think it'll do well 2 weeks lull for a week or two till the general public hears about the controls, you might see some of the FPS crowd buy this in addition to Halo while you get the standard metroid crowd....
