Well, I was thinking about this for a while now and I wanted to know what you guys think.
Lets start with my prediction for certain character move set.
What if Diavolo was able to SWITCH back and forth between Doppio like Tira from the Soul Calibur series
It IS the same company producing it so I think it be a create twist to his move set. It'll show people who the REAL schizoid is!
As for some of the crisis modes (like GER) we could also have : Made in Heaven, Love Train, Another One Bites The Dust, Jolyne's Mobius Strip, Echoes act 3, Heavy Weather, Alternate Diego. They might even throw in Silver Chariot Requiem too.
as for who I think is left to be revealed
Part1: Dio,Speedwagon,Tarkus,( Bruford is IFFY but if Yukako's in it then it could be hair vs hair)
Part 2: Lisa Lisa and Stroheim
Part 3: Joseph,Iggy,Vanilla Ice
Part 4: Koichi,Rohan,Akira,Fatty and Yukako
Part 5: Bruno,Narancia,Trish, Diavolo/Doppio,Cioccolata and Risotto
Part 6: FF, Annasui,Weather,Pucci and Versace
Part 7: HP,Diego(Scary Monsters),Valentine,Soundman(if not Wekapipo)
Part 8: I personally think he'll be the only one in his part since it won't be far into the series yet.
As for WHO I think the mysterious character that Aya Hirano will voice..
my moneys on Yukako or Trish (more likely Yukako though)
