Sony could release PS5 on 2017 for all we know. And looking at what we know so far on Scorpio there isn't anything there that PS4Pro couldn't have if they wanted... Instead of downclocking they would overclock the GPU, Add a new set of GDDR5 for 12Gb... there is nothing inexistent, only not cost effective for this year.
So in 2 years if Sony is willing to change architeture of their GPU and CPU they could have another big improvement on HW. The limitant factor for both companies was just full compatibility.
And on MS discontinuing support for X1 in favor of Scorpio they could be sued because they promissed that all games that works on Scorpio would also work on X1.
