I agree with 159.2M sold for PS2 but I think it's rather interesting that Sony declares that every console has "More than..." in their official Worldwide sell-in.
Makes me think "how much more" for some of these.
Thankfully VGChartz does a great job on data, we get a good solid idea, based on facts, mathematics, and hard work.
Lifetime Sales Predictions
Switch: 160 million (was 120 million, then 140 million, then 150 million)
PS5: 130 million (was 124 million)
Xbox Series X/S: 54 million (was 60 million, then 57 million)
