I love you all to death (Just so I can smash bros with you) (SSBWiiU/3DS)

I honestly don't see what the problem is, I doubt they will cut or reduce characters from the Wii U version just to suit the need of the 3ds.
The might make complex characters less complex, Wario has one costume, Nana doesn't attack, PT doesn't exist (but his pokemon have their slots) etc.

Characters take up such little of the game data, all the stages, items, and various modes take most of the space.

Didn't SSE take up a huge part of the disc (which is why you can't mod things in it on homebrew)

I mean the stages in the 3ds version will be different, and if they keep it simple with just a classic mode and a verses it shouldn't have a problem.
