With 1 character being confirmed in my original prediction (Steve) and one getting disconfirmed (Travis), I think now is a good time to check what change and what I think of the last remaining 4 of my original prediction that I did back in March.
-Ryu Hayabusa: by far the one that I'm the more confident that he will get in. With Tecmo working with Nintendo on Hyrule warriors age of calamity, and Nintendo pushing Atelier Ryza 2 (especially in Japan), it seems clear that Koei tecmo is now a important partner to Nintendo. Alaco according to Vergeben, Nintendo did talk to Koei tecmo about Smash. While that could end up with nothing, I feel confident tha Hayabusa will get in eventually. He's pretty much the face of the developpers and has a big legacy so I'm sure he wil be chosen before a Atelier rep.
-Dante: Nothing really changed for Dante, although with Min min confirming that Sakurai is open to add content from already represent franchises, and Monster getting not only one but two games, I might have underestime Monster hunter chances. That being said, it's possible that Sakurai was pleased with Monster hunter being rep with a boss, so he would go with DMC. DMC 5 is also getting a next gen enhanced version, which show that Capcom think that the franchise is pretty important now. I still think Dante have more chances than Wright considering that nothing changed for Ace attorney.
-Arle: Like Dante, nothing really changed for her. She's getting a new game later this year on switch, which might help a bit, but she already had a strong presence on Switch so it probably don't matter that much. Streets of rage 4 got a revival, which was a pretty big succes, but I think this was way too late to being really consider into Smash as a playable fighters. Yakuza is another honorable mentions, but with still no sign of the franchises to touch a Nintendo console, I think Puyo puyo will have priority.
-2B: Probably the one that I was the least confident, I'm still unsure about 2B. Square is seems to pushing way more the Nier franchises right now, especially in the West. Unfortunately, she stil don't have any Nintendo presence, although that might means nothing. I still think that 2B is the most likely Square rep if do get one more, considering that Bravely isn't really getting any push and I still have doubt about Geno except if Nintendo really want to please the fans.
So in general, aside from 2B who I'm quite unsure, I still feels pretty confident in my original prediction. Of course, I'm not pretending that I will have predict everything and that no other charaacters than those 4 have a shot, but at least my original prediction all have decent chances of getting in, with Hayabusa probably having bigger chances.
