Xbox exclusives like Deadlight got a PC port, and State of Decay will be getting one later this year also.
and that's just off the top, there's plenty more......unless MS owns the developers of those games
(last I heard they don't own Capcom or Crytek) and decides on not releasing a PC port then anything is possible
PS4/PC heads most likely gonna eat off some of those Xbox One "exclusives" eventually......... Games like the Uncharted series, God of War, Last of Us, Beyond Two Souls, Gran Turismo, Heavy Rain, Infamous second son, etc will NEVER get PC ports.
If you're a serious "gamer" nerd and a fan of quality titles then this is the safest and most sane route, if u just want to cop 3rd party sports titles and play COD online all the time then I guess it really wouldn't matter which path you take though.
