I think Marth will be at least as prominent as Sothis. I'm less certain how much screen time any of the other ring characters will get. It is fairly typical for Fire Emblem to have a bunch of characters that don't really contribute much to the main story and only really show up in supports after their recruitment chapter. Although, some of that is to get around the fact that characters can die for good. I assume ring characters can't actually die or be lost for good so the story can always assume they are around.
