IMO.
All PS3 games are undertracked? No. That's not the case.
Others consoles games are undertracked? Yeap.
But PS3 games seems more undetracked than 360/Wii games? Yes... just read the next question.
Why?
Sony has been selling games in a lot more countries than Microsft and Nintento and there are just three big tracking services for VGC correct your data: NPD (US), MC/Famitsu (Japan) and Chart-Track (a few contries in Europe) .
So VGC is a very good and accurate trackin service for US, Japan and few contries in Europe (UK, German, France, etc)... but it receive no data from Latin America, Asia and Middle east.
Because that the games are undertracked... and that affect more PS3 because it had more sales in Latin America, Asia and Middle east than others consoles.
And GT5?
The first shippement was 5.5m and the second shippment happen in 31th Dec... so in 31th Dec GT5 sold near 5.5m to force Sony to ship more 830k million.
VGC had GT5 at 5 million in 31th Dec... so seem a little undertracked... I guess 300k in EMEAA (not in big contries but the small combined).
See ya.
