It'll be #1 in America, that's for sure. Worldwide, probably not, especially if they announce the NextBox to be released in 2012 at the 2012 CES in a couple months. If they push the release to 2013 like I think they will and do a nice price drop in the Spring of 2012 ($150 - 4GB Xbox 360, $250 -250GB XBox 360 bundle & $350 Xbox 360/Kinect bundle) they might have a chance. Do to the Wii U coming out next year, the original Wii is pretty much done. The Wii will be dropped to $99 after the Wii U launches. The PS3 still has the momentum during the off months and it's mostly because Microsoft doesn't release many must have exclusives during the off months. M$ should have 1-2 exclusives ready to launch every month, with Oct - Dec seeing 2-5 exclusives in those months. I would bundle every critical exclusive (i.e. Halo, Forza, Alan Wake, Fable, Gears etc...)
