Sorry, there's a typo in there that probably contributes to the confusion.   So....

Because of the PS4 Pro and Xbox one X coming in the middle of the generation, some portion of the consoles sold were sold to people that already owned the original version each of those consoles. So, 80 million PS4 sold does not mean 80 million different people purchased PS4s. Several million of those are people that bought more than one.

I was mentioning this in relation to the Xbox 360 replacement comment. Certainly, the Xbox 360 numbers were inflated to some degree (moreso thantusual) by people replacing their broken systems.  I think the mid generation upgrades have a similar effect on sales numbers in this generation.  I just don't know to what extent.

Thanks I understand. But I think there is something you forget. Actually I think people who upgrade their console sell their old model to other people. I see this a lot.

I mean it goes something like this : 2 people want a PS4, one buy 2 PS4 (old model then the upgrade model) and the other one don't buy a retail PS4 but buy instead a used model, so it doesn't count at the final sale. So at the end it's 2 console sold only for 2 people.

Am I making sense ?

Yes. I understand, and agree.  But, certainly not every person that buys a Pro or an X sells their original console.  We'd never be able to figure out exactly how many people fall into that group.  also, some people in every generation by more than one of the same console, as they may want one in multiple rooms. The point is, the mid generation upgrades are just another unknown factor when trying to determine the actual user base of a console.
