Sweet tapdancing Jesus...
Have you ever worked in production of any kind? Then you should know that there i no such thing as increasing production over night.
For example : you want to produce more switches, then you need to produce more plastic parts. You need moulds, so that is 8-12 weeks at best. And since no factory worth its name has machines standing empty , waiting for Nintendo to call, you either wait until the factory/ies has production time to sell or you invest in a machine. That is 3 months if the machine is anything customized.
So at the three month mark you have produced 0 extra parts for switches.
You have to do a Production Part Approval Process , so that is another week.
All this is for increasing the production of just the plastic parts.
Now i imagine that Nintendo is faster than this, but anything close to 1 month is amazing.
How do i know this? I manage a plant that is producing plastic parts.
And for the "open more factories" crowd : call any quality machine producer for injection molding and say you want 6-8 Big customized machines "fast" and watch as their fast is in a diffrent dimension than your.
And i bet that noone that uses the artificial scarcity argument has ever worked in a sales position. Demand is there now, maybe not next week or month, so any product that is not on shelves right now is a potentially lost sale.
Nintendo did not run a successful company for more than 100 years by gambling.
