No. Nintendo uses their own tracking system company not related with NPD or GFK. ioi thinks the Nintendo tracking is more accurate... comparing it to NPD I guess he is right (NPD tracks just 60% of the US market), but I guess GFK is more accuracte after all (tracks 90% of the UK market) but GFK doesn't show numbers, just positions. |
I can't find them but when we had expanded results they clearly based graphs on NPD numbers.
edit: I found some older stuff:

Look at what is described as source for graphs.
