I could agree if there was no superhero options on Xbox but it's far from being the case, i dont think most of us would want any of their actual studios to have to be working on some Marvel or DC IP, them working on gaming IP or simply new IP is perfect.
Plus we're already overloaded with these things on the cinema industry, not sure how repeating this on the videogames' one would be good, i get they sell well but oof.
Playstation has to and will be the console for superheroes, but as i said, as multi we're getting new Gotham, Suicide Squad, the Avengers, Guardian of the Galaxy, that Firexis marvel strategy game, the Wonder Woman one, the TLOU's co-creator one, next Netherealm's fighting game will 100% be superhero stuff etc, i mean we've been getting 1 superhero game announced per month in the second half of 2021, and many more to come.
