Fifa had Xbox exklusive marketing, Sony exclusive marketing, Xbox exclusive marketing again and maybe Sony exclusive again. Don't see it as a big deal.
Same with CoD, same with Assassins creed (not confirmed yet), same with Battlefield / Battlefront, same with GTA / RDR, same with Resident Evil. Basically every major 3rd party game changed its marketing rights between MS and Sony to whoever pays more for it.
I really think, that it doesn't really make a difference at all at this point.
Imagine not having GamePass on your console...
