Honestly with how Sony is winding down PS4 hardware so much, 2021 could be the final year PS4 sells over a million units. It will probably manage a few million by the time this year is over. And then probably about half a million to three-quarters of a million in 2022. Then really low after that.
It looks like PS4 will outsell Game Boy+Game Boy Color, but not near as easily as we thought. Until about nine or so months ago, it seemed like the PS4 could reach 125-130 million lifetime sales.
Lifetime Sales Predictions
Switch: 151 million (was 73, then 96, then 113 million, then 125 million, then 144 million)
PS5: 115 million (was 105 million) Xbox Series S/X: 57 million (was 60 million, then 67 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)
