I don't believe it. Even if it is true it would not be as great of a W as you think. Did you forget Death Stranding? So did everybody else, so I don't blame you.
Hideo Kojima was fired form Konami because of his ego and we saw that very same ego during the development of DS, months and months and month and months with nothing about the game but we did have the announcement of a 30 sec logo load up, game engine adventure, toyline, collabs, and strange for the sake of strange trailers. I remember when they finally showed gameplay footage at TGS I was so unimpressed that I thought Kojima was MGS2 level trolling us. Nope it was the real deal. Kojima definitely lost a lot of prestige and is just another Japanese developer that failed to find the level of critical and commercial success he did when he worked on the IPS that put him on the map. There is no reason to be excited for a Hideo Kojima game.
Death Stranding does look like a walking simulator to me but according to reviews it’s a pretty good game. So Kojima has made mostly masterpieces and one game that is still considered good but not a masterpiece that’s a pretty good track record. MA getting a legendary developer to debut a game on their subscription service is a major W for them. I’m not even a big Kojima fan but if this is true I’ll definitely check it out on gamepass.
