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.

"In short, yes, we're still going to release DayZ for PS4," the representative said. "It's mostly that we have the ability to do the Game Preview program with Xbox that has us choosing this platform for the first console release, and the partnership with Microsoft has been very productive so far. We're still excited to have DayZ in the hands of PS4 players, it'll just happen a bit later than the Xbox release."
