or...now that I think of it, isn't this familiar?
THIS IS EXACTLY what apple did with the transition to arm.
They are gonna spilt the x86 space for preparation for big little since arm is a threat.
They will keep win 10 supported (2025) till machines before 2018 get their upgrade cycle, now that i think of it....and due to how many new standards focusing on power efficiency and security..i think microsoft is trying to split things up and begin a "new generation" following atx 12vo, big little, and arm implementations.
I might've screwed up my theory but u get the point, windows 10 is still there i mean...*inhales deeply*
