So far i realise some MvC3 roster almost look identical from MvC2 roster (since i already notice) but not just about the character , even same moveset for each character, for example:
Blackheart - Dormamu
These guys almost same identical moveset (Projectile spammer). So it could like this:
Those character had been confirmed by bringing back from MvC2 roster:
Ryu
Chun-Li
Morrigan
Felicia
Wolverine
Ironman
Hulk
Captain America
Dr.Doom
Spiderman (not confirm yet but he tottaly in)
Those character are unconfirm from MvC2 will be transfer to new character:
Blackheart - Dormamu (projectile spammer)
Dhalsim - Super Skrull (Rubber guy, teleporting, fire element)
Tron Bonne - Volnutt (Drill attack)
Cable - Chris Redfield (Too many weapon)
Jill Valentime - Frank West (Zombie summon)
Captain Commando - Crimson Viper (same identical moveset)
The clone (same identical moveset) character will be not in MVC3:
Ken
Akuma
Dan
Sakura
Wolverine Bone Claw
War Machine
Charlie OR Guile - depend which character you choose
Some character not confrim yet but it will replace new or bringing back if moveset, character design or special ability look same:
Storm - Thor (it's unknown if Storm is really confirm by Seth but bringing two electric character with the same time, depend on it)
B.B Hood - Deadpool (Both are "best joke" character but Deadpool's moveset same as B.B Hood does like bomb, gun, sword but with crazy attitude
)
Sentinel - PTX from Lost Planet (I hate to say this but it seem giant character are not gonna be in this game. The problem is Sentinel, Sentinel doesn't same PTX height state, maybe Bloodia could make it?)
Sliver Samurai - Soki or Date Masamune (It make sense if Sliver Samurai wasn't confirm but replace with "new" samurai character, depend if Soki return as TvC model or Date Masamune as the new character)
Zangief - Alex (If Zangief was deconfirmed, maybe Alex take his spotlight but bring Alex's TvC model is like completely lazy (If they create new moveset), MvC3 need grapler character)
Servbot - Viewtiful Joe (It doesn't make sense somehow, just because they look small body but big head?)
Cyclops - Ryu (I don't know why Nitsuma rule out Cyclops, maybe Cyclops same Ryu does? Why not change another moveset, geez ~_~)
Some character that i don't know if same moveset or character design, there will be replace or return, here the list:
Cammy
M.Bison
Megaman
Roll
Anakaris
Hayato
Jin
Strider
Amingo (deconfirmed)
Ruby Heart (deconfirmed)
Sonson (deconfirmed)
Venom
Magneto
Rogue
Gambit
Marrow
Spiral
Thanos
Shuma Gorath
Colossus
Iceman
Juggernaut
Sabretooth
Psylocke
Omega Red
BTW as for Cable, i say Chris might replace for him, but what about Saki from TvC? Chris don't have Viper beam but Saki does?
