Microsoft is the 4th biggest corporation on the planet, and even with tech prices and shortages they could absolutely get Xbox 5 out by November 2027.
I think Sony is going to wait until November 2028. Xbox 360 and Switch went 8 years before being replaced, I think Sony can do the same at least once. PS5 Pro has also bought Sony a little extra time, as well as subscription and software revenue and profits.
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: 122 million (was 105 million, then 115 million) Xbox Series X/S: 38 million (was 60 million, then 67 million, then 57 million. then 48 million. then 40 million)
Switch 2: 120 million (was 116 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)
