Just thinking from Capcom side, they port bunch of platforms but this only to Switch really? I mean porting same game to PC and PS4 wouldnt cost that much would it?
Who really knows. They reuse assets from one Generation version to the next, so nothing is stopping them doing a port for other system. Will they do it? Capcom don't really like to risk or step out of their comfort bubble but E3 might be different when MH5 gets talked about.
