Recently, there have been rumors that Sony might be looking to follow Microsoft's footsteps and start embracing PC releases for their 1st/2nd party exclusives. Recently it was reported that Horizon Zero Dawn is coming to PC, but that is an old game now, not too big of a deal for most people. However, recent job listings at Naughty Dog suggest they are hiring programmers with Nvidia GPU and PC programming experience, which may mean that Sony is considering embracing PC releases on newer games as well.
