"Through official channels the current sales quantity (which I can't share, so don't ask) is considerably better," said Lee who added he's "not sure about vgchartz's methodology."

 

VG Chartz has shown itself to be consistently accurate when it comes to hardware sales, unfortunately software charting remains a bit inconsistent.  This is different than when NPD complains, this is a publisher.
