Well, considering that is pretty confirmed that 3DS is overtracked by minimum 1 million, i show you why.
The Japan numbers are correct, and we all know...
For the US numbers, easy, we have VGChartz VS NPD.
2011
NPD: 4.08m
VGC: 4.10m
Pretty good track.
2012
NPD: 3.65m
VGC: 3.61m
Looks like is undertracked this year (in the US)
2013
NPD: 3.83m
VGC: 4.04m
~200,000 overtracked...
2014
NPD: 2.54m
VGC: 2.65m
another ~100,000 overtracked...
2015
NPD: 734k in 13 week
VGC: 674k in 12 week
2015 seem ok.
2011 to 2015, we have 3DS overtracked by ~300,000 in the US.
But as we all know, the problem IS NOT the US... is the Europe.
We know that the Nintendo console in the US sell more than in Europe, that is fact. so, if we see the YOY sales US VS EU...
2011
NPD US: 4.08m
VGC EU: 3.6m
Seem correct... a 10% difference is probabily what is the 3DS sales US / EU.
2012
NPD US: 3.65m
VGC EU: 3.82m
What the fuck? 3DS in Europe above than US? No, just no! at least ~170,000 overtracked (but is more...)
2013
NPD US: 3.83m
VGC EU: 4.10m
Again? this time 270,000 in Europe more than the official US sales, so, at least ~270,000 overtracked...
2014
NPD US: 2.54m
VGC EU: 3.00m
Seem that the overtracked is increase all year... o.O this time probabily ~460,000 in Europe...
Seem that 2014+2013+2012 3DS is overtracked in Europe by att least ~900,000... +1 million seem correct.
So, we have 2011 to 2014 3DS over by 300,000 in the US, and by +1,000,000 in Europe.
Adding NA / RW , maybe +1,500,000 overtracked?
Yeah, seem correct imo... so, we can say that the 2015 sales are (as for now) around correct, but in the first 4 years, 3DS is overtracked by 1.5m to 2.0m
WHAT DO YOU THINK?
