Playerunknown's Battlegrounds is one of the biggest games on the planet right now, and it's coming to Xbox One later this year. Microsoft reached a deal with developer Bluehole to bring PUBG to Xbox One first, though it could come to PlayStation 4 later. Now, Bloomberg is reporting that Bluehole is having discussions with Microsoft about "extending their agreement to publish the game exclusively on Xbox."

This information is sourced to people who asked not to be identified due to the private nature of the supposed discussions. The report goes on to say, citing the same sources, that Bluehole is apparently looking to have PUBG be exclusive to Xbox One on console for a longer time period than originally planned.
