Capcom has trademarked the name, Fighters of Capcom, suggesting that we may soon see a new title from the publisher.
It's not often that Capcom fighters all clash with each other, so perhaps Capcom has decided to release a game which does just this. The trademark is for use with computer game software, so it's definitely relating to a game of some sort.
In Japan, GREE released a crossover card battling game named Capcom AllStars, so maybe it's a localised version of that? Or perhaps Capcom's working on its own Smash Bros style game? Who knows, we'll no doubt find out soon though.
