Additional details:
- This info is 3 months old. from a Capcom UK source who communicates with a source at Capcom USA
- Leaker admits he
might be being passed misinformation and counterintelligence as a part of a campaign by Capcom, says that might have happened to other leakers too (named Ryce), and Capcom used this to also gauge interest, so take these lists as a combination of just ideas, launch characters, and actual planned DLC
- Oct 10, 2017 release date
- UMvC3 Port will be announced today to gauge interest for MvCI, potentially even a MvCI announcement today
- Aiming for 35 characters to start, odd numbered character is Ultron infected with Sigma Virus
- Will have unplayable additional characters in the story mode.
- Most of the default Marvel costumes take from Marvel NOW!
- 4-6 colours per character, alts will have individual colours you can pick between
- Felicia censorship by Marvel, Disney and ESPN to make the game more presentable/eSports
- Marvel is not trying to see midnight Bliss
- Hard at work at making netcode the smoothest and most stable they've ever made
- Idea of cross-costumes was pitched at some point
- Stages will be mashups, one that might happen is the Ace Attorney Courtroom in or taken over by Hell (Ace Attorney/Ghost Rider)
- Story mode will have a lot more attention to detail and less useless characters than SFVs
- Decision on mechanics post-X-Factor and TAC was to have more controlled chaos
