It's not about a foundation, rather, cost. They aren't going to implement something like that unless they plan to charge you an enormous price for it.
Do you believe a custom DSP type of chip like they use in Hololens would cost a lot. Also, MS is at their best when they are behind instead of leading. In other words, I believe because they have so much room to make up with Sony that they would be willing to go all out but still stay in that 500 buck terrority. It is predicted that MS will have multiple consoles not just one coming up next gen. This could be the balls to the wall edition. Personally I would like to know the cost of the hololens co processor to get a ball park price point.
