I stand by 105 million or so, surpassing the Wii and PS1. PS5 has direct competition from the Xbox Series S/X which surely will have higher lifetime sales than the Xbox One. Then it has more indirect competition from the Switch, and in another few years or so the Switch's successor (Switch 2? Super Switch?) will be another form of indirect competition.
The PS4 benefitted from the failure of the Wii U and many blunders of the Xbox One. That's why even with the PS5 currently outpacing the PS4, I don't think it's quite enough. The direct and indirect competition is stiffer this time. Also, remember when many of us thought 125-130 million or more for the PS4 was a given? And now it will probably finish with 120 million or a little more. The same thing could happen with the PS5. It could reach around 100 million or less and then only sell 5 million or so units once the PS6 is out.
Lifetime Sales Predictions
Switch: 156 million (was 73, then 96, then 113 million, then 125 million, then 144 million, then 151 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)
