After hearing Kojima Production as second party to SONY, lol i doubt it will be easy for PS fans looking out for another consoles, maybe a gamer that have not decide will be the new target for Microsoft and Nintendo.
But Wii U doesn't have any chance and NX will competing with PS5 in the future obviously (it will not directly competing with PS4 ). But Xbox they always has their Ace card (money ) they always can buy every studio out there with a risk (loosing money 
)
But if Microsoft want they can just integrated AR Hollo lens to Xbox One, but i am doubt that will happen, because it will be to expensive for their fans to buy (more expensive then VR). But anything can happen, because Sony can just f**ed them self, but still SONY has learn a lot from the past.
Need to be worry though is another competitor outside mainstream gaming market which are Apple, and Google.
