God, I hope not.
Nintendo has made tons of money on Switch hardware, and will still sell more. 100 million is a given, and 115-125 is likely. They'll also sell tons of evergreen first-party games. But I don't want the Switch to cut back a lot of first-party software yet, especially after a disappointing 2020.
Lifetime Sales Predictions
Switch: 144 million (was 73, then 96, then 113 million, then 125 million)
PS5: 105 million Xbox Series S/X: 60 million
PS4: 120 mil (was 100 then 130 million, then 122 million) Xbox One: 51 mil (was 50 then 55 mil)
3DS: 75.5 mil (was 73, then 77 million)
