IMO:
Dante
- Staple and major Capcom property. Everyone likes Dante & watching Dante play
Doctor Strange
- Will be a prominent part of Phase 2 of the MCU, and I can see him making an appearance along perhaps Black Panther. Also he's cool. Maybe Dormammu will come with if a standalone movie is made, who is also pretty unique. Maybe Nova now that we have the first hint of a possible Nova in the MCU.
Frank West
- I don't think Dead Rising is going away anytime soon, and he's unique and recognizable enough to the masses that they will buy in. Maybe Chuck, or whoever, but I can see a DR rep doing a whole bunch of stuff that Frank does will get in.
Wesker
- RE is another huge property and Wesker has resonated more with core fans and casual observers than other RE characters. Also very popular character in gameplay.
Thor
- Now that he's here, he's not going away anytime soon in games that will have Cap and Iron Man guaranteed. With Marvel reintroducing it's properties to the masses and Thor getting decent reception, this is a lock.
Viewtiful Joe or Amaterasu
- I don't know which, or if both, but at least one of Clover's children will return. Capcom still likes these characters as much as they may not be ready to commit to anything with them.
Capcom side is harder. Zero might get replaced by a real Megaman. Spencer is basically irrelevant, even the rearmed version. Arthur seems like he won't fly again in the future without a backer like Seth and Viper is uncertain because there's already so many SF characters and I can't see her making it in over Ryu/Akuma/Chun priority, though it'd be nice. That spot could just go to a SFIII rep depending on who they feel like they should be nice to.
With Marvel, MODOK has been quirky and couuuuld make it in again because of the crazy unique playstyle, but its more unlikely than likely. Can't really make compelling arguments for the rest and a few are a product of their time, and I'm sure Capcom doesn't want to deal with the Phoenix headache again. Balanced or not.
