It's so awesome that everyone reads the first post, which makes the incorrect assumption that ioi assumes all of his data is perfect and never corrects it, which is wrong, and then they just post without reading what anyone else had to say.
Several people in this thread pointed out that the YTD numbers for VGC and NPD agree, that the console manufacturer shipment numbers are in line with VGC, and that VGC data is corrected every couple of months (Xbox 360, it seems, is usually corrected downward).
