Well I can only speak for myself but I definitely won't be buying a XB1 anymore, whereas before I was considering it. I have an ok gaming pc that I've periodically updated over the years so its definitely XB1 level of power, and so pc gaming is an option for me.
Having said that, whereas before I was considering buying a XB1, now I'm definitely going to buy games like Forza and Gears, so from MS pov I'm gone from a maybe customer to a definite, which is a win for them.
Personally this is what I've believed MS should always have done from the original Xbox onwards, there was never a need to abandon PC to prop up Xbox, but MS did it abandon PC for many years, and in doing so lost sight of one of their greatest strengths.
