Wow all of this is just so stupid, nobody knows for sure what the exact numbers for Microsoft are, they said 'over' 66 million, i'm not even convinced they're giving sold numbers but are infact giving shipped numbers even tho they're 'claiming' otherwise.
On top of that nobody has any idea at all what Sony's numbers are for all of October-December & there figure of over (again not exact) 3.9 million worldwide for the holiday period may or may not include every single region they sell to as they sell to so many more smaller regions when compared to the competition & they may or may not have included some of them.
NPD is tomorrow & i can almost guarantee there will be adjustments from that & in a months time the actual official shipment data comes out, & only then will people know who 'won' the year. Until then claims of victory and any 'adjustments' made now are all incredibly foolish.
