There was some confusion as to the state of Dead Rising 4's exclusivity overnight, but that appears to be cleared up now: the zombie zapper will feel the festive spirit on the Xbox One and Windows 10 this December, with a Steam release to follow 90 days later – and a PlayStation 4 launch lined up for next year. The game will apparently be a "console exclusive" for 12 months, so expect to be playing it on Sony's system in December 2017.
The terms of the arrangement are exactly the same as Rise of the Tomb Raider, which is still yet to be dated for the PS4 by the way. To be honest, Dead Rising 4 probably would have been better off skipping PlayStation entirely, as the franchise has been so on-and-off on Sony's devices that it's never really established a fanbase on the formats. Still, this may come as good news for those of you who want to play the game, but aren't in the market for a new console.
