VG numbers are 718,784  for Americas.

560 for the US and 160 for the rest , sounds very accurate , well done

So , why do people seem so surprised ?!!

EDIT: Unless if I'm messing things up.

EDIT2: Nope I'm not, it's actually 700,000 - 750,000 in Americas.

They had GT5 at 694k for US in December and 1.106m in total in US.

So we now know it did 400k in November NPD and 560k in December NPD which means lifetime sales for GT5 in US are 950k.

Which means VGC in comparison to NPD have it 150k over-tracked in US. Or just under 10%.

Of course that isn't that much. And US isn't GT5's main region. EMEAA is. But if it is over-tracked in a far easier region to track like US then it does make you wonder how acurate the numbers in hard to track places like EMEAA are.

I thought VG definition of US was larger than NPD coverage - i.e. VG should always be larger than NPD as it includes broader Americas vs USA centric NPD.  Or have I got it wrong?
