This is according to reports out of Japan where Nintendo president Shuntaro Furukawa warned that supply could be affected. According to Furukawa, he notes that while the company saw strong sales performance towards the end of 2021, he suggested that for 2022, the company might not be able to keep up with demand.
Furukawa was quoted as saying, “It will depend on demand, but as I feared, we won’t be able to make the amount of units we wanted to.” The company had initially forecasted that they would ship as many as 25.5 million units for the fiscal year ending in March, but they later lowered that to 24 million.
It’s not a particularly huge change from their initial forecast, but it does indicate that the company is worried that they might not be able to meet the demand and don’t want to provide numbers to investors that they won’t be able to fulfil. This isn’t to say you won’t be able to find a Switch if you wanted to, but it’s something to keep in mind all the same.
