Microsoft released the shipped number for the quarter (1.7 million)... VGC is pretty accurate... so no adjustments needed (maybe NPD is wrong).

NPD usualyl wrong? I thought they were super accurate.

It more accurate than Media Create / Famitsu and less accurate than Chart-track (or the Nintendo tracking).

NPD just tracks 60% of the US market... 40% is estimated... just to compare Chart-track tracks 90% of UK market (this is super accurate).

NPD make adjustments month to month too.
