If they do, probably by 2022. Xbox One has about 0.75-2 million left in it, I think. It might just barely pass 50 million.
PS4 is performing a little worse right now than I expected. 130 million doesn't seem possible right now unless Sony changes up its strategy. On the more pessimistic end, PS4 has about 6-8 million left. On the more optimistic end, 11-13 million.
Sony's strategy with the PS4 right now is baffling me. Both the PS4 Slim and PS4 Pro are still at their prices of $299.99 and $399.99. They need price cuts.

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)
