Are Wii U sales figures here hard copy only?

[DélioPT]

Given Nintendo`s data, the difference between sold SW and the data here is just too big to have so many SW on shelves.
Still, it`s the next best thing and seeing as there isn`t a reliable source to add digital sales to VGC sales, there`s no blaming the website.
I rather take what i can get than nothing at all!
