Before the quarantine started i would've predicted 125m, now it's very hard to predict. It can't go much over that, it's the end of the life for PS4, but it could possible get to 130 million and maybe a bit over that.
Right now i'll just say 125-130 million, closer to 125 million.
2020 predictions: NSW 25m, PS5 6m, XSX 4.5m, PS4 11m, XB1 4m
In December 2019 i predicted 21m Switch, 9m PS4 and 3m XB1, but that was before COVID, obvius increased my predictions.
