Three houses is probably gettinga rep in the dlc. They do not have spirits yet and we do not know how post pass will be handled. They could do a fighter pass 2 with only third parties while they give us some nintendo characters, like dixie, bandana dee, fe rep, or astral chian with only the character and music.
Personally I have conflict opinions in the representation of FE in smash.
![Marth :ultmarth: :ultmarth:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Marth: He is great. The first lord, sword user wih light speed a veteran since Melee. His inclusion while questionable before is now irrelevant considering how huge Fire Emblem has become. Marth is also loved by the comunity, not as popular as other lords but his games in DS have make enough for the people in the West to know his character and fell in love with him.
![Roy :ultroy: :ultroy:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Roy: Lucky Boy, if it weren't for Melee he will probably be with Seliph, Sigurd and Leif as the most forgotten lords in the franchise, his game is still a japan exlcusive an does not have a remake like exhoes that bumped Alm and Celica popularity on the comunity.
However this story is another and despite of being a bland and useless,
he was very bad, chatacter in his games to the point of being one of the primary reasons to not play Binding Blade, Sakurai make him flashy, energetic and added some fire moves that give him the personality he never had so now is a fan favourite both in Smash an FE comunities.
So now I think he is fine as a Melee veteran and is distinct enough of Marth to consider him as his own character. He literally is almost an Smash original since he debuted first in melee than his own game, so do not make him leave his true home.

Ike: Good choice before and good choice know, a very distinct moveset than Marth making him a proper "second" rep of the franchise. His heavy attacks and more agressive personality reflect his mercenary status. He is loved in both comunities. In the FE comunity he is the most popualr lord and his games are considered some of the best in the franchise despite the abismal sales. A good representstion in my opinion.
![Lucina :ultlucina: :ultlucina:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Lucina: The first "official" clone of Marth, we alredy had Roy so another clone was questionable, but he was very, VERY, loved by the FE comunity so i guess Sakurai tried to put her by all costs even if she weren't her own fighter. Now I think with overall aceptance of echoes Lucina is not so much hated by the Smash comunity, specially with the preference of top players for Lucina in ckntrast os Smash4 days when barelly anyone used her over Marth, she has gained her spot, and represent one of the most important games for IS: Awakening. But we had another character to do that..
![Robin :ultrobin: :ultrobin:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Robin: A huge suprise considering the popularity of Chrom, but for me it was the right move. He had so much more moveset potential than Chrom and it represents weapon durability, magic, dark magic, a different class, the types and changes of weapons, even the types of spells, a lot of things in the franchise are represented trough robin, so while he is not so popular in the fanbase, he is an important inclusion for the roster of Fe characters and a perfect rep for Awakening in my opinion. That game at least deserved one character for not letting the franchise die.
![Corrin :ultcorrin: :ultcorrin:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Corrin:
This is the problem. Fates was even not out yet, and the character was not requested, but they put him in at the worst possible moment. They were argues over the size of the Fire Emblem roster before but Corrin was the thing that really upset the people. They were all expecting and praying to have theri favourtie character in the game, knowing it will be their last chance, they have askin for years and then a charavter than no one wanted, with a series with too many characters, from a game not even out yet, to "steal" that precious oportunity for your character, what an amazing Smash villain Sakurai and Nintendo created.
Corrin could have a unique moveset in contrast of the other FE reps and represent the manakete part of Fire Emblem, but he never should have been a character. He is hated everywhere. Almost all the FE fanbase consider him the worst lord of the series and the primary reason of the bad writing in the Fates games, myself included, so if he was not added probably no one would ever requested him, not even now. And in smash well Ihave explained it alredy. Despite FE being my second favourite videogame franchise of all time I am not okay with his inclusion, specially the timing, literally every other FE lord would have been better and it should have been added in ultimate not Smash4. But he has gained some love nowadays, his moveset is fun and the female alt is cute so a similar situation with roy has happened, but with the origin of the hate for a roster from a not so well represented franchise. I would cut him personally if it would be another smash game, and give his moveset to another character like tiki or myrrh.
![Chrom :ultchrom: :ultchrom:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Chrom: He was requested but I think it is an overrepresentation of awakening with three characters from one game of a the whole 16 games of the franchise. However he is an interesting echo different enough to roym so is meaningfull to pkay one form the other. He does not bring harm or good is only another FE "clone". I would have put someone like alm to represent more games in the franchise but chrom is not a terrible choice.
So now I think FE has the curse that most of hsi characters are clones or semiclones that do not rpresent well the obrrall franchise using mostly one fo the various types of weapons, and representing with 7 characters only 5 games of the franchise. I woul really love to have a Threehouse rep that bring somethin unique to the table and is loved by both the FE and Smash comunities, so it does not matter for me if is Claude, Byleth, Dimitri or Edelgard, as long as they represent well Three Houses as a whole, is now my favourite game of the franchise, I will be happy and perhaps it could finally erase this undeserving hate the franchise in Smash has showing them that is more than just "anime sword fighter".
