Most likely if they were to incorporate it, It probably end up being through a
use of a Capability Tool to incorporate it -via- those using DirectX-12 Ultimate which will make it easier to incorporate all the new technologies in such things as ray tracing, more intense shaders, etc into games for developers but of not just games of course, supposedly this
Direct-XII Twelve Ultimate will give the ability to incorporate into older game \ give the ability for developers to incorporate this into thier older games as well but currently in its coding phase looking for coders to work on this to make it work for use, That is if you some-what keep up on whats going on with technology + the futures of technologies its headed and yes, including games.
If I think anything else to write whenever or how long that may be due to not coming to the forums + not as often as I used to, I'll simply either edit it in or contribute it into a new post.

{edit}: Granted you can even find some of this under NVidia's News + Info. pages or posts gone into the news Media posts as well but not just NVidia and Microsoft though...
