SSB4: Who do you think/hope is going to be on it?

With the recent confirmation of SSB's 3ds and WiiU sequel, i bet we're all wondering what new characters it'll have in store. Who do you think or hope is going to playable? Obviously, the chances of a character like Naruto or Sora from KH appearing are very slim so keep your predictions realistic, but I'd also like to know who you'd like to appear. :3
