It is rumored that Marvel vs Capcom 4 is currently in development and will be launched sometime in 2017.
Polygon claims that Marvel vs Capcom 4 will be announced this weekend during the PlayStation Experience. During which the Capcom Cup 2016 Street Fighter V tournament will be taking place.
It seems that instead of the X-Men being featured like they typically do; The Avengers will actually have the spotlight along with The Guardians of the Galaxy and possibly characters from Civil War. It’s still just a rumor so far, we’ll have to wait for this weekend to see if it’s true.
