@apujanata, I am not really defending VGC or my article title, I am just pointing out that simEx members would have know already that VGC's # are estimate, and are not in synch with NPD #. It have been proven quite a lot in the past, and I am sure it will happen again in the future.
The latest case of VGC not in synch with NPD can be found in July 09 NPD, for Mario Kart DS, the worst offender. VGC estimates 61,787, while NPD report 132,200 (53% error against NPD).
