I would possibly buy that in the case of the Wii simply because of the demand being far beyond anything that Nintendo had previously experienced but I do not buy this for the 3DS. Up until this year, Nintendo had been manufacturing close to 10 million 3DS units yearly and this was the first year that Nintendo was really tapering supply. A little bit of foresight back in July could have shown Nintendo that they could have easily sold another 8-9 million this year and I think that they could have easily contacted their suppliers and asked for a return to the previous year's shipments without a lot of extra cost (maybe they wouldn't have gotten quite 10 million but I think they could have got a lot more than 6 without the need for any new factories being set up).
The fact is that Nintendo DOES make a lot of business mistakes and you don't have to be a wallstreet exec to see them. We wouldn't have gotten the Wii U if Nintendo knew what they were doing. Nintendo did absolutely nothing to harness the INSANE popularity of Pokemon GO. The one thing that they could have done was to leverage the newfound popularity of Pokemon by making Pokemon Sun/Moon a massive hype-fest, instead the wind gets taken out of their sales due to a lack of supply. There is no way that you can convince me curtailing 3DS production in this manner was a smart business decision during a Christmas seasonwhen the Wii U is literally selling zero units. I think that the real problem is that Nintendo is especially out of touch with their western market. They really do not know what is popular and what is cool here and by the time they figure it out, it is already too late.
So, you claim they are just stupid and that no business element (supply, wharehousing, Switch, ROI, etc...) played a role.
