If PUBG isn’t an XBO exclusive, this wouldn’t be PR; it would be straight up lying and false advertising.
When has that ever stopped a publisher/developer? Raiden V MOSS said was staying on Xbox..1 year later it just came out on PS4. Capcom said Dead Rising 3 was exclusive to Xbox then a year later came out on PC. RE4 was supposed to be Gamecube exclusive. Ubisoft lies about it's visuals every year..hell even Naughty Dog does and lie about thier AI. Sony insisted TLG was coming to PS3 and not PS4. A million more examples.
