It won't, Nintendo should have pulled all the stops and make a "second launch!" making sure millions would be available. Buuuuut.. it probably was 2 boxes of 7 again per location of reseller, while apps that keep track of stock, notify all the scalpers there has been a "new delivery".
No working aprent will be able to get them LOL.
ANd yes that is NINTENDO's fault.
They by now know the intensity of the demand, so they can produce like crazy. But they choose not to. If done right, and with production revved Nintendo should be able to sell 20 million in the first year even. As it ticks off all the boxes for a success, a nice bundle during Christmas would really push people over. But nope....
