Images have leaked showing Dead Rising 4 running in game. These photos apparently show in-game content.
Dead Rising was originally exclusive to Xbox 360. After selling well, Capcom went multiplatform and released its sequel across Playstation 3, Xbox 360 and PC with a spinoff on the Wii. After the second and spinoff didn’t sell very well, Capcom wasn’t going to release a sequel. However, Microsoft obtained the sequel rights and funded it, while Capcom developed it. This was why Dead Rising 3 was exclusive to Windows 10 and Xbox One.
It is unknown if the fourth title will be exclusive to Xbox One, but if the title is once again funded by Microsoft, then its likely it will be. I guess we will see at E3.
