It should outsell the Xbox360 by 3-3.5 millions if things keep going this way ( expect abyssmal Xbox360 sales for Holydays 2008 in Europe the way things are going...)
NA : Xbox wins by 1 Million
Japan : PS3 wins by 1.5 Million
Other : PS3 wins by 3 Millions.
During 2008 Holydays PS3 software sales will tie Xbox360 software sales ( not LTD, but it should get there during the holyday period). That will happen mainly due to others...
2008 will be the peak for Xbox360 sales, sales will stay good in NA in 2009 but Japan+Other sales won't be worth being mentionned after 2008....
