Nintendo’s latest export has completely exhausted its initial inventory of stock [..] Moreover, the Wii U only had a couple of weeks on sale in November
So, it was only on sale for part of the month, and it sold out quickly, leaving consumers unable to buy. OK, so it's a pretty much useless comparison, then?
I'm highly skeptical of the claim that it sold out. Both Wii U SKUs are easily available in most of the US right now. Supplies were constrained initially, but that has more to do with scalpers buying up every preorder in anticipation of another Wii-style fad, which has clearly not happened. If you look at Wii U auctions on eBay, the few auctions that complete have been selling essentially for cost once eBay fees are factored in.
It may have only been on shelves for 12 days, but people were free to preorder it all month, so you can't just divide the total sales by 12 and apply that to the other 18 days.
Also, a lot of people probably bought it for resale since it's the holiday season and the first new console in 6 years. Prices on Ebay are barely above retail though, so demand doesn't actually seem to be outpacing supply by very much.
If it had been on sale the entire month and (assuming) they maintained the same rate of sales as it did the 12 or so days it was available, it would have sold around 1.06M units.
I would imagine they could have made up the 200K difference their had been more inventory.
