The biggest issue is that VGChartz puts its corrections out there -- while most people don't see what changes NPD makes.
Also, NPD has no Toys R Us or Wal-Mart data from this generation ... so it is using estimates only on the two big fish.
Is VGC 100% accurate -- of course not. But people act as if NPD is -- when it is not (compare actuals to predicted by analysts if you don't believe it).
And if people don't believe you can make a giant statement based upon a small sample, they missed the fact that a properly done survey of 1000 people could predict how 100M plus were going to vote in the recent US Presidential elections (and also that one of those with the more questionable results was done by GfK).
