That wouldn't even make sense. MP and Warzone are still tightly integrated (only way to practically level up your guns for one thing). The battle passes still mesh together as well as the cosmetics.
You'll see Xbox get the same stuff that Sony has been getting for years. Extra XP boosts and such (which are annoying but far from industry breaking).
If MS takes COD exclusive, I'll call them out on it. I just don't think it will happen. MS isn't going to win people over that way, and they know it. They've tried the heavy handed stuff in past gens and we all know how that turned out for them.
As I said too, if I was a salty PS fan, I'd just buy a PC, because there really is no exclusivity anymore. (this is also why it is not a monopoly). If they were trying to sell every Xbox they could, they would not put all their big "exclusives" out on PC.
