PS4 is creeping toward the Game Boy/Game Boy Color. If Sony actually lets the hardware live a few more years, it might manage to surpass the GB.
Switch has surpassed the 3DS. I remember the time when I thought Switch would tank as hard as the Wii U or manage NES sales. Those were early on.
Xbox One is creeping toward 50 million, and I think it can pull it off.
It will be interesting to watch the Xbox Series and PS5 take off more when there are less supply constraints and more next-gen games.
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)
