UPDATE 3/12/16: Marvel vs. Capcom Infinite has been announced, right on time at PSX.
We were only given a brief teaser, but it showed Iron Man, Ryu and Mega Man. More details are coming over the weekend at PSX.
UPDATE 3/12/16: An online report has indicated Marvel vs. Capcom 4 is due out in 2017.
Polygon's sources said the crossover fighting game will be unveiled at Sony's PlayStation Experience event this weekend. Eurogamer's own sources corroborated the report.
Polygon reports that unlike previous games in the series, MvC4 won't feature X-Men characters. The game will instead stick to Marvel's cinematic universe.
So, no Sentinel Rocket Punch cheese. No Magneto madness. And no Cyclops Optic Blast. A shame? Perhaps!
But! Expect Groot, Rocket Raccoon and the other scamps from The Guardians of the Galaxy to appear in the game. Oh, and Doctor Strange, too.
Capcom currently has close ties with Sony for its fighting games. Street Fighter 5 launched on PS4 and PC only, and Sony backed the Capcom Pro Tour with marketing and tournament support. With the Capcom Cup 2016 finals set to take place at PlayStation Experience, Marvel vs. Capcom 4 could also be tied up in Sony console exclusivity.
