A better example why you didn't can compare the Nintendo EU numbers with VGC EU number directly.
2011 Nintendo EU
PS3 ~ 4.9 M
360 ~ 3.7 M
2011 VGC EU
PS3 ~ 5.8 M (+18%)
360 ~ 4.2 M (+14%)
Using the same ratio for 2012... VGC should show these number for EU to be inline with Nintendo:
PS3 ~ 5.1 M (~300k undertracked)
360 ~ 3.4 M (~400k undertracked)
That's my maths.
