I feel, if we’ve learned anything from the Wii > Wii U or even the Wii U > Switch, it’s gonna be a new game. The only shot there was at porting a smash game was 64 on the Wii VC and before Iwata talked to Sakurai about making Brawl.
Smash 6 is looking more of a reality now
Tbh I really hope it’s a port because I think ultimate itself is fine as a game, it just needed a few more patches in order to be more playable for everyone. Regardless of what it is, I also hope they make huge improvements for online
I would also like to believe that a new console will mean less native input delay for the next smash game
