Seece said: Xbox 360 IS overtracked 1.6m in the US, NPD has solid tracking that covers 95% of the market. |
Where did you get that? I know MS said 1.6m and VGC shows 1.7m right now for US in 2013? Do you have the lifetime numbers?
If it is true then your numbers starts to make sense 
but WW it is more like ~500k undertracked... the regions balance seems more under/over.
