Guesses on Legendary Hero for September

First of all, good to know that I nailed two out of the three heroes in that banner!

But unto the topic, I've gone around and compiled all the possible options for Legendary Heroes this month that could use a blue weapon (with every option available)

FE 2 (Celica with a blue dagger (would make no sense as she just had her alt)
FE 7 (Eliwood wielding Rex Hasta, also unlikely due to every other character getting a Legendary Hero weapon from their countries, Durandal for Eliwood in that case)
FE 10 (Micaiah, with some super Thani)
FE13 (Grandmaster Robin (preferable a dude) with some blue tome)

Now, if you're asking why I didn't include Fire Emblem 1,3,4, 5, 6, 8, or 9. Here's my reasoning.

1-3 Caeda is a useless character and similar to FE6's Lilina, only talk a bit and then remain silent for the rest of them game, not netting her any important story purposes.

4-5 Altena is an option, but she isn't a lead, that would be Leif, and he wields a different weapon (Bragi Sword) and as such I fail to see them not giving him that weapon when they didn't give him the weapon on purpose in his first iteration

6 Lilina thoug popular is fire oriented and she is also not a main unit (just like Caeda) talking a smidge but then remaining quiet the whole game, giving no reason to make her a Legendary Hero.

8 Eirika's legendary weapon is bound to be her Lightning Siegelind (counterpart to the flaming siegmund) and as such will be a red unit. She can't wield lances either, and it is unlikely that she'll become any other unit type due to her only using Swords and Magic by lore.

If you wanna prove me wrong for any of these because I don't know what I'm talking about, go on ahead. Also, keep in mind, even if you wish for a unit such as Ishtar, or something like that, unless they have major plot purposes (IE they show up alot, not sparringly) then they won't have a shot. So do keep your reasoning down to earth, as to not get our hopes far too ahead of ourselves XD

If I had to pick I want. I want Grandmaster Rob. If I had to pick a guess, Robin as well. Micaiah and Celica just got their alts. Eliwood is getting Durandal eventually, and no other unit that I recognize is going to let go of their prf weapon for a lance, blue bow, blue dagger or blue tome. That is, unless IS choses to give us Celica or Micaiah this time around, in which case they will double up on alts. If I had to pick, ignoring past alts, I'd say Micaiah. It makes sense to me.
