Some people are still undecided about who won 2011, even Reasonable who's word I would take over anyone else's.

But doesn't VGC say that the PS3 won by 300k, and NPD say that the Xbox 360 was 900k units more overtracked than the PS3, suggesting that it won by 1.2m?

Am I somewhere on the right lines?

NPD is not world wide. ALSO VGCHARTZ GUESS'S IT'S NUMBERS, SO DOES NPD. Um yea they really don't know the real numbers, it's a calculated guess. So who is right? The company that has the numbers or the people trying to guess the numbers. Does anyone remember the past, this place has been a mess. Numbers have been off and it's been by alot. 

even if it's shipped that would put 2.4 million on the store shelfs. Like the comment above explains.

I know NPD is not worldwide, I'm just including the changes to US sales, hoping that VGC's tracking everywhere else is accurate.
