Reasonable on 25 February 2008
I think it may slow it up but I'm not sure GTA IV will drive that many extra 360 sales. After GOW, Bioshock and Halo 3 how many people are left in US without a 360 who will buy one because of GTA IV? I can't believe its enough to seriously slow Wii down in overtaking 360 sometime around June/July (assuming that WiiFit and SSBB drive a reasonable increase for Wii, which seems likely).
Try to be reasonable... its easier than you think...
