Earlier this year, Chang Han Kim had already suggested the idea of making PlayerUnknown's Battlegrounds a universal franchise on all types of platforms. In particular, he said in an interview with our friends at Invenglobal that the Xbox One version was only a temporary exclusive.
With that in mind, it's possible then that PlayStation 4 and Switch versions are currently in development. This is what one Reddit user claims, adding that the game will be adapted to the features of the latest Nintendo console:
"Late this year PUBG will be coming to PS4 once the Xbox Build is Ready to go Gold and in 2019 a port of the new mobile Build of PUBG will be optimized for the Nintendo Switch with Support for Amiibo and will also have Smaller Maps for Local Play up to 16 Players but Full Size Maps will also be Playable Online or with Bots the game will be running at 1080p and Capped at 30 fps with Support for Gyro Aim and HD Rumble (Keep in mind that this is The Mobile Build of the Game with extra Features.)"
This is still a rumour, of course, and Bluehole / PUBG Corp. have not confirmed anything, so don't get too excited just yet and take everything with a pinch of salt for now.
