Though many had assumed Red Dead Redemption 2 would run in 4K on the PlayStation 4 Pro, Sony and Rockstar have confirmed this to be true.
Via the PlayStation Blog, Sony has posted the six minute gameplay trailer of Red Dead Redemption 2 that was revealed this morning with the text “Captured entirely from in-game footage on PlayStation 4 Pro, watch this introduction to Red Dead Redemption 2’s gameplay in 4K.”
An identical caption can be found beneath the YouTube video itself on Sony’s official account. The same video was uploaded to the official Xbox YouTube channel, though its caption is slightly altered, reading “Captured entirely from in-game footage, watch this introduction to Red Dead Redemption 2’s gameplay in 4K.”
