Ok I read all of these comments and a few things to note:
1.) I agree with the fact that Square Enix costumes were the majority for Square Characters when the Mii Costumes came up, however that doesn’t mean other Mii Costumes can show up during the presentation so there’s that.
2.) If Ryu Hayabusa shows up as a Mii Costume in Sephiroth’s presentation then that most definitely means there will be no Koei Tecmo rep in this Fighters Pass, they would almost certainly not put a Koei Tecmo Mii costume in another companies character unless they were not getting a rep. If it happens where there is no Hayabusa Mii costume tomorrow but Kasumi shows up as the Koei Tecmo rep and the costume is released there, then that would make sense but if it’s just Ryu Hayabusa as a Mii Costume tomorrow then that means that this is the only Koei Tecmo representation in this pass, that’s it and that would piss me off.
3.) For the lol’s yes Kasumi’s design would most certainly be from DEAD OR ALIVE 6 as that is the most appropriate one
4.) I’d like to trust that Nintendo thought of Koei Tecmo and their partnerships together but in the end of the day it’s Nintendo’s decision on who they want to add to Smash or not and if they just gave them a Mii Costume then honestly that would be a major diss to Koei Tecmo considering how much they’ve helped Nintendo with Hyrule Warriors, Fire Emblem, Marvel Ultimate Alliance and more, you’d think that they should give them a playable rep and not something as demeaning as a Mii Costume
UPDATE: Sephiroth might be coming with only two Mii Costumes, if that’s true then it will be looking good for Ryu Hayabusa
