During a special episode of Inside Xbox, which was hosted from within its gamescom 2018 booth, Microsoft announced that Playerunknown’s Battlegrounds will soon exit its Xbox Game Preview program.
When the above occurs, PUBG will not be delisted. Instead, it will become a full fledged title. Thus, it will have “Full Product” status, as the press release calls it.
Playerunknown’s Battlegrounds will become a “finished” game on September 4th.
