It'll still be CoD, Lol.
Modern Warfare 2 beat everything last year as per usual in US NPD even Elden Ring which had massive hype behind it and came out 8 months before it and the same in Europe, after CoD it'll probably be Fifa as per usual, I wish there was a year without a CoD/Fifa so it would make things more interesting.
After that though, it's a tossup between Diablo, Hogwarts Legacy and Breath of the Wild 2.
Spider-Man 2 after those, it'll be hurt by being PS5 only unless the attach rate is crazy.
Weird how you said Starfield will be huge and we all forgot how big Bethesda games are and here you are not even mentioning it.
