Any sellout is a good sellout, although it's likely that the anti-hype about the Wii U going into the holiday season against the mondo hype for... everything else could have caused more or less all retailers to under-order, after having half a year (or worse, in Europe's case) of stock sit around from last Christmas.
So it could be that Nintendo overstuffed last year, but undersold this year...
