A PC of almost any performance level/price today, with all the Xbox One exclusives on it, is simply a superior Xbox One. There's literally no reason to buy or play on an Xbox One if that was the case.
Sunset Overdrive would certainly sell better on PC, and before long it'd be a dubious proposition to even make it an Xbox One game in the first place.
You're in a position where you elect to play on Xbox One even when given better options - for whatever reason - but it doesn't change the fact that this would make the system infinitely less attractive. Simply count all the posts saying they would sell their Xbox One, or the ones breathing a sigh of relief having "dodged" buying one.
It's great for MS if they can just drop the Xbox system all together and still claim the benefits of owning the "platform" games are released on. It's great for gaming "overall", and the viability of every great game if everyone can play it, like I said in my reply. But better for the Xbox system itself, or better for fans of the platform expecting to be able to buy an "Xbox Two"? Just no. All of the no.
Putting some titles that make sense on PC on PC down the line, and making them cross-buy - that would be "good for Xbox". But day and date circumvents the Xbox One completely, and it'd be even more parenthetical than it already is.
