The combination of Kinect, Xbox 360 Slim, and continued non-Kinect games for 360 all led to Xbox 360 selling so many units. I'm pretty confident the total of 85.73 million units of Xbox 360 goes down to 70-76 million if Kinect never existed. People would still buy 360 for the software and Xbox Live, but Kinect wouldn't be there to add to the appeal. PS3 might even hit 90 million lifetime in this case, or a bit more. Wii probably sells a few million more and surpasses PS1 slightly.
Xbox One is in a better spot. It would retail for the same price as PS4 at launch and would probably sell millions of more units. I don't think it's hitting 70 million, but it could hit 65 million units or more. Kinect was an issue with Xbox One, but PS4 was just firing on all cylinders.
I really don't know how it all affects Series X/S. Maybe they do a little better too because of Xbox One selling better in this alternate scenario.

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)
