For the japanese cover of super mario. i think the 4 means can play up to 4 persons with one cartridge (if the caracter for people is the same as in chinese).
Else for super mario bros mii. i don't know why but i think about a cross game between wii U and 3ds.
But we must first concentrate ourselves on the way to entertain people, for video games to live. Else, it's a world where sales representative will win, which has as effect to kill creativity. I want to say to the creators all around the world:"Courage, Dare!". Shigeru Miyamoto.
