They will keep the 2:1 sales relationship and Sony won't have to react.
I believe more and more that the PS5 will be a proper console generation and not compatible with neither the PS4 or PS4 Pro. I'm not sure about it, but I'm not as convinced about this "blurring of generations" as I was when Microsoft talked about it.
One big reason to believe this is the PS4 Pro's weak CPU. I think it's too weak to support the most advanced games that are developed for release in 2020 and onwards.
I hope this is the case, and that Microsoft is forced to follow suit, because obviously future games will be able to be more advanced if the lowest supported system is the PS5/Nextbox rather than a PS4 Pro with its weak CPU.
A PS5 as a reaction to the Scorpion is crazy talk because there simply won't exist hardware that is much faster than the Scorpion or even PS4 Pro for use in a console in the next couple of years. What's the point of a PS5 that is only double as fast as a PS4 Pro? That would be a huge disappointment.
