Dead Rising 4 has today been confirmed for an Xbox One and Windows 10 release, with no mention of a PS4 version being in the works which is not a surprise given the partnership Microsoft have with Capcom.
NeoGAF user Gwyn said that it would be released during the holidays of 2016 for the Xbox One and Windows 10 on a forum post earlier today.
This means that there will be no PS4 release and the game will stay on Xbox and Microsoft platforms only.
