Ok then time for the nasty stuff
VGC NPD Difference Wii - 577k 557k 20k Overtracked (3% over) 360 - 416k 338k 78k Overtracked (19% over) Ps3 - 394k 313k 81k Overtracked (21% over) Psp - 142k 119k 23k Overtracked (16% over) Ps2 - 74k 118k 44k Undertracked (60% under)
The PS2 is infact severely undertracked by a significant margin. Wii is spot on with a 3% variance whilst the Xbox 360 and PS3 are just slightly outside of the acceptable margins which I call as around 15%. The PSP closer.
Which means both 360 and PS3 are not selling anywhere near the high numbers currently VGC has them acording to NPD. I find that most interesting as we are lead to believe on here the demand is high, especially for the PS3.

Ok I have made adjustments using the rough VGC = .90 for NPD comparison formula. Im editing the % now.

You just used the 90% formula on numbers that were already reduced. So your first post was correct, VGC had huge overtrackings for March.
See the NPD preview, clearly, these are US-estimates: http://news.vgchartz.com/news.php?id=7761
It's also stated clearly in TheSource's first post in this thread.
