So what I'm seeing is:
DS overtracked around 350-400k
Wii pretty much right, maybe 50k undertracked
Wii U also around correct, maybe 100-150k undertracked
3DS massively undertracked around 700-1000k
So not too bad on the Home Console front VGC, a bit of corrections to be made on the Handhelds. It seems like these issues are indeed coming from Europe, as we expected.
