User blog comment:KimKilWhan7/How DLC would (most likely) work/@comment-12408658-20140916224613

I'm guessing once the Wii U version comes out a free DLC/update comes out for the 3DS version and you get 5 characters, 2 stages, some trophies, etc. I'm guessing it will be 1) Mewtwo 2) Lucas 3) Dixie Kong 4) Wolf 5) Chorus Men

Also everyone Ice Climbers can never be in SSB for 3DS/Wii U, Sakurai already said that they can't program too characters at once due to the limitations of the 3DS.
