>ARMS representative
Very likely, probably Spring Man since he's the "main" one.

>New Street Fighter character
I really doubt it. Capcom would probably want to represent some other franchise instead of doubling down on one. That's what I think anyway.

>Castlevania
I also doubt it a lot, even with the Simon Belmont rumours. I was amazed Snake was allowed back.

>BoTW
I think Link himself is that.

>New Final Fantasy character
I think Sora has more of a chance now that Noctis is in Tekken.

>Echo Characters
Like I said in another pic, I think Dark Samus wouldn't be an echo, his Assist Trophy moveset is already very distinct from Samus'. I could see Ken happening but I'd rather Akuma.

>New Xenoblade Character
Very likely and it's probably gonna be Rex. I'd prefer Pyrrha/Mythra tho.

>New Capcom Character
I'd say it's likely but I have no idea as to who it could be. Also Nintendo and Ubisoft have been really close lately, maybe Rayman actually has a shot this time?

Longshots are longshots but I'd love them.

I actually doubt ARMS will get a rep, remember the inkling in smash 4? it didn't even got a character as dlc, we had to wait for this new smash, and Splatoon was more popular than ARMS, so I feel like, if we were gonna have an ARMS rep, it will be either as DLC or just a mii costume.
