There is no "Upgraded" version of Tekken 7 but it will run on the Series X. What the OP is talking about is games upgrading automatically to a "next gen" version. If there's no next gen version it just plays the game as is on the current console with slight benefits from the better hardware.so for example I have Tekken 7 for XBONE, All I gotta do is put in in my Series X and I'm good to go?
