Yes, it’s coming westward
Monster Hunter 4 Ultimate is still coming in 2015 outside of Japan, and there’s yet another Nintendo/Capcom crossover coming. A Samus costume is making an appearance, and yes, it will be coming to the western version of the game.
At this point I think Nintendo and Capcom are friends enough where the latter can just, give over the rights to Mega Man games to the former? I mean, think about it. Capcom can pull a George Lucas and retain merchandise rights. Nintendo can make great games and Capcom can still collect — do a five to ten year deal and see where it goes.
