@Zerosaurus: Actually VGChartz uses the same methods as any other who estimates sales. Including NPD.
@Viewsonic: Don't you think you're jumping the gun a bit too early. There are few things to consider:
1. This site used to use NPD numbers, but NPD threatened VGC with a sue, so VGC had to drop the NPD numbers and collect its own. So, i think you understand why VGC doesn't jump everytime NPD says so. THAT situation would be a joke. Besides, VGC doesn't even try to match NPD 1:1.
2. VGChartz likes to collect it's own data, even that it sometimes is off a bit from others data, it's still the only way to get this site trusted on it's own. I remind you that VGC isn't very old yet.
3. When ioi adjusts his data, he doesn't just "adjust it", he want's to find out what went wrong and make the adjustment after he knows what to adjust. After all, it's not just the frontpage data that gets adjusted, it's the history too. And since ioi (quoted in this thread) said, that PS3 sales came as a total surprise, expect ioi having a lot of work to do before he makes the adjustment.
4. Backtracking was also mentioned in this thread. If VGC would just use others numbers, eventually the numbers would be off, considering the data, where there are no access to "totals".
So a little reasonability and patience. I've personally been on this site long enough to know, that the numbers will be corrected as soon as the numbers are properly analyzed and ioi knows what to fix.
