The OFFICIAL Feb 2007 NPD Thread

[Diomedes1976]

I have one BIG doubt FOr the PS3 numbers the NA aggregate of vgcharts is made of simply adding the US and Canada data given by NPD .Allright . But what happens with the X360 and Wii data .....it is WAY HIGHER than adding the data from those two sources ?For example the X360 sold 228K in US and 12K in Canada for a total of 240K....whre does vgcharts come with the extra 20K sales ??
