The only way I can see Sony delist there games on Steam is they make a PS PC launcher & players who bought the game can make a PSN & then when login in to your PSN on the PS PC launcher it detects you bought the game on Steam or you had access to the game & PS gavem ex Steam users a ticket to get the game for free on the PS PC launcher but the seems like a whole fiascoit'll be too late to change strategy, most of their franchises are already on PC
