I don't necessarily disagree, but I think they are holding out on us.
Getting CYS/Ash/Chizuru back on the base roster as well as Isla & Dolores is probably enough to sell the game for most people, but outside of that it does feel very very familiar in terms of roster choices. But they have already said that there are multiple DLC teams and I think that's where the big time fan favorite picks are going to lie. Like, people will definitely shell out the DLC money if American Sports Team comes back that way.
I also think that there's just an unfortunate amount of pairing down they have to do. Bringing back all dead characters AND having so many newcomers in 14 AND still needing needing have the expected standard KoF teams is just too much possibility space. I think its a shame that Hein, Alice, Najd, Nelson, Zafina, and Sylvie might not come back, but are they gonna nix Team Ikari to make room for them? Nope.
