Thanks to MW3 and Skyrim (somewhat), the 360 was able to clase the overall gap by ~115K. However, given it wasn't the 230K needed from last week's estimation and there is now 1 less week, the amount the 360 has to outsell the PS3 by each week has gone up.
As of week ending Nov 12th - 9,519,074(PS3) - 8,025,387(360) = 1,493,687 or ~249K over the PS3 for the next 6 weeks.
