Why is there so much difference between sony psp shipments and VGC data?
sony total psp shipments ->61.5 m http://news.vgchartz.com/news.php?id=80014&mp=1
VGChartz Hardware data for the period 05th Dec 2004 to 03rd Apr 2010: 57,632,824

But nintendo ds shipment ->128.89m http://news.vgchartz.com/news.php?id=79945
VGChartz Hardware data for the period 21st Nov 2004 to 03rd Apr 2010: 127,966,736

Also, for comparison:
PS2 Sony total shipment 144.5m http://news.vgchartz.com/news.php?id=80014&mp=1
PS2 VGC sales 136.40 http://gamecharts.vgchartz.com/hardware_totals.php
in short, why the difference between Sony and VGC data are 3.868m aprox., and the difference between Nintendo and VGC data are 0.924m aprox. (with last financial results)? Are there 3.8 million of PSP in stores?
