DayZ developer Bohemia has confirmed that the survival-action game is still headed to PlayStation 4, though players on that platform will have to wait a bit longer. A spokesperson for the developer told GameSpot that Xbox One owners will get the game first because the platform has an Early Access-style program, Game Preview, while Sony's PS4 does not offer anything like this.

The 1.0 version of DayZ will launch in 2018 alongside the Game Preview version on Xbox One.
As for the PS4 edition, players may want to get comfortable. Bohemia said on Twitter that it cannot guarantee DayZ will launch on PS4 next year.
