I'm still salty that Nintendo doesn't separate Game Boy/Game Boy Color sales. And for that matter, I think significantly different iterations should be broken down in sales.
For instance
-Sales numbers of the PS4 Pro vs Standard and Slim
-Sales numbers of Xbox One X vs. Standard and S (Normal/All-Digital)
All I know is that the last several years of Game Boy were almost surely all Game Boy Color since even if Game Boy Pocket was somehow still available it had to be in tiny amounts.
Lifetime Sales Predictions
Switch: 161 million (was 73 million, then 96 million, then 113 million, then 125 million, then 144 million, then 151 million, then 156 million)
PS5: 115 million (was 105 million) Xbox Series S/X: 48 million (was 60 million, then 67 million, then 57 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)
