Back at the time the poll's were taken it was four months old (Think on it...Ranking top 10 and having sakurai's interest for both twins in a game that was out four months while the other characters...Well most where there for YEARS AND YEARS AND YEARS.), Now it's about a year and a half old...Anyhow FE Is likely to get 2-4 (Probably 3-4 since it has a huge fanbase , 3 Is more likely.) so they already have ike which was highly requested and brought upon an international sales release for it , We are probably getting marth due to his importance and high regard , So this leaves minimum slots left (But you missed the point , With it having many lords it's very hard to represent them all so they have to represent the "Most important" But with Mother it's easy to sneak in 2 For it's best selling one.)well how old is mother 3? since when did it exist? I keep on thinking it's a new game :O
and Fire Emblem does have many Lords, if I could decide for that section I'd pick 5 lords, one for each system Fire Emblem has been in.
As to what ves said yes sakurai has been intended to do so SINCE Smash 64

Which is my point i'm trying to make <_<.
