I have an idea I'd like to see in that game.

As I keep repeating, the DS Zelda games are underrated and underrepresented. It would be so nice to have a stage where you would fight on top of the Spirit Tracks train while cruising in all four realms of the game. Oh yeah, and it would be with the stage hazards seen in the game (and hopefully you'll have the possibility to turn them off in the next SSB). And let's not forget that this awesome music would play:

If Toon LInk is in it would make sense to add stages from the zelda ds games. It's a good idea, awesome music.

DRILL DOZER is my number one pick

most likely character:
bowser jr
miis
waluigi
rosalina
daisy
funky kong
dixie kong
dry bones bowser
female pokemon trainer (with johto starters, but could be any starters really, most likely the new gen of pokemon)
dark pit
birdo
King K. Rool (may have problems with rare, but dkc return character should have no problem)
professor layton
custom robo
little mac
balloon fighter (bring back classic characters like ice climbers, game and watch, kid icarus, but if little mac is in the game that may be the classic character even though recently released and wii game)

Possible character:
paper mario
toon zelda
baby mario and baby luigi (fights like ice climbers)
sin and punishment characters (a fighting stage from this series would be cool)

more most likely general characters
more pikmin, probably pikmin guys brother (if pikmin 3 is release for the wiiu, then expect more pikmin)
a female character from starfox
more characters from kid icarus
a villain from F Zero (if a f zero game is being made for the wii u, then expect some more characters in the series in the new smash bros game.)
game and watch girl (ah how cute)
more fire emblem characters
more metroid characters

Really likely characters:
the armadillo, samurai, and pushmo from the 3ds ware game. they will be somewhere in the game for sure. if nintendo is planning to make a sequel to these games most definitely they will have playable characters in the game to advertise their up coming games. the armadillo would be a great character and be able to replace sonic.

i hear that nintendo is working on new characters for new series of games for the wiiu. if so, they will definitely be on the wii u smash bros game for advertisement.
