You're naive if you think that's true.
Minecraft is a children's game, the optics of pulling it would be disastrous.
I've said it before and I'll say it again in my very strong opinion, warzone (including future versions) will remain on playstation in perpetuity, the next couple of mainline entries will come to playstation, with the first exclusive coming the first next gen release, maybe something like xbox series xyz, but only a ps5 release to ease in.
Mainline entries will have unlockable bonuses for warzone, enticing users to switch over, starting at the tail end of this generation.
Of course a lot can happen in that time, like sony developing a legitimate war fps contender, forcing cod to stay, but as it stands, cod was never going to be exclusive in perpetuity.
