My guess on the five DLC characters:
- XBC2 character: It's clear Sakurai wants a character from this game in Ultimate even though they haven't started any work on the DLC I'm pretty sure someone from the game will be in Ultimate.
- Virtua Fighter Character: Akira made it into ultimate as the representative for the series that was the first 3D fighter but only as an AT I can see someone from the series being picked out as a main character.
- Fire Emblem Three Houses Main Character: Really you don't think this will happen?
- Jin (Tekken): SEGA got Akira into the game I'm sure Namco could do the same with their iconic series as well.
- Dante (DMC): A bit hopeful tbh but it makes sense to go along with Bayonetta.
Not so bold prediction: The will be another character pass after this one.
Ultra Hopeful: Some SNK representation.
