Batsute
The Lion Choker
Capcom needs to come through with the same TLC that they put into MH, DMC5 and RE2 and 7 with Street fighter.
Going hand drawn high res 2D would be the unique pop they need. Plus everyone remembers. SF as a 2d thing.
The focus needs to be it being huge with attention to details and story/single player content.
The problem is you can't really sell out fits and mods for that.
Anyway it would be a huge risk, but the industry is lacking a beautiful hand drawn 2d title. The way social media works it would get a ton of attention of being 2d alone.
Beautifully drawn 2D sprites, with a finale to a 5 year story arc with a highly praised fighting system.
Ask SNK about their pockets after they released KoF XIII.
