At this rate, with Sony releasing Neo later this year, and Scorpio being rumored for Fall 2017 MS will already be late as Sony will simply release a PS8k 2018/19.
And I expect Sony to stress that this is not a new platform or new generation. They will simply talk of this as an upgrade to their existing ecosystem.
And then MS releases a new Xbox in 2019/2020...
You see there is no really counter in this discussion anymore? Who releases first has worse hardware than the one coming late.
It's basically the question When will I upgrade my PC.
