I already tried to get information about how vgchartz gets its data and they don't answer to me, so I'm still willing to believe that an independent consultant like AC Nielsen is more accurate than this website, until I have some evidence that proves the opposite.

It's funny because PS3 is 200k units above and Wii 200k under AC Nielsen figures (660k Wii and 410k PS3). A weird coincidence. All the media here in Spain (press, web, tv) have the data (and I got a copy of those sheets since the study is public) and the differences are too big to ignore (DS 2,1 million in VGCz to 2,6 million in Nielsen and PSP 1,5 in VGCz million to 1,3 million Nielsen).

The data says clearly "sold to consumer until dec 30th 2007", so ioi please explain to me why this data is not accurate, and yours is.

 So, Vgchartz uses GfK data did you say? Any source?

Thanks ^^!
