The King of Fighters
That's fine. If you look at any series the people will change from game to game.
Uncharted 4 has a bunch of different people working on it, that doesn't mean its a "b" team or it won't have the soul of the other games
I think Director changing or total dev change has proven in many games to show a noticeable difference in direction and nuances of a game, usually for the worse, unless the initial game had problems or it was just a remaster or something. But if it's moreso the changing of the guards of the low-level peeps, then it's probably not going to be a big deal.
