Shadow Of War and Assassin's Creed Origins are the only big third party marketing deals they got. So those two and Forza 7 are gonna be they big pushes for the X. I wouldn't be surprised if the TV ads for AC and War end with "Played best on Xbox One X". But I wouldn't be surprised if both Shadow of War and Assassin's Creed sale better on PS4 simply due to having twice the install base.
