Numbers befor adjusted right ? Coz i think they have adjusted. Also is this for U.S or Americas ?

these are numbers for US only from both as for VGC there the numbers are from there previews there were some adjustments for june and july i found in there later previews, its impossible for me to get the rest unless ioi or source want to come in here and help out, NPD dont adjust theres so whats there is permanent

i did add these june-july adjustments into the totals for 2010 at the bottom

Well all i know is that next week =

VGC and NPD are both using retail sample data.  Calling one less accurate than the other doesn't make any sense when both are highly calculated estimations.

Say VGC says 700 and NPD says 900.  But the real value is 800.  Can you look at the NPD number anc alim VGC to be any less accurate?

VGC's USA numbers are Americas X 0.87. Source has said so a few times.

:edit: But as you can see here our Non-USA ratio seems to fluctuate a bit from 0.13.

without a shadow of doubt

But going by Price is Right rules, in this case VGC would be the winner.

As much as I love VGC and the work the team does, NPD are the professionals. They are the biggest market research firm in the world. Lots of different companies ask them to track sales and pay big time for this. Not just videogames of course. They track pretty much everything.
