MS's goal now is to capture what they can of the PC market and maintain their Xbox brand, so whatever Xbox gets, PC will get over time as well. To them making and buying games for both brands, than making entirely exclusive and separate games for each platform, is cheaper for them. Besides I don't see the other two doing the same where they make exclusive games for OC and then their own console.
As much as I dislike MS at the moment with their overall vision with Win 10/Xbox, I honestly don't see them getting a leg up in anything. THis gen has been mapped out and set in such a way that only one system will "always win", or "always be on top", no matter what the competition does (don't need to look through plenty of threads to see that message as clear as day).
Mankind, in its arrogance and self-delusion, must believe they are the mirrors to God in both their image and their power. If something shatters that mirror, then it must be totally destroyed.
