Should PS3 be adjusted up?

[Zlejedi]

Something in the numbers doesn't make sense.

Wii and X360 have shipments for Q2 at level of their sales which means retailers haven't made any additional supplies for Christmas, the only way PS3 number makes sense is if we assume sellers were stocking for Christmas but if they did so only for ps3 then it'd imply they were having low stock of PS3 which doesn't make sense if we compare lifetime sales of PS3 to lifetime PS3 shipment compared to Wii and X360 which had much lower stocks.

So either PS3 is undertracked or X360 and Wii are overtracked in others or a combination of those factors. Which makes sense if VGC aproximates sales in areas almost impossible to track based on sales in western europe.
