Just some of my kind of unrealistic fantasies:

Wouldn't it be cool if you could use midna she would be pretty cool and maybe link could morph into a wolf

Rampage wasn't that good of a game but imagine having one of those mutants in the game.

Maybe since lethal alliance is on the DS nintendo will finnaly include a star wars character in ssb

Another cool thing would be virtual console characters now that would rock

Dragon ball Z characters would fit pretty well into super smash bros goku or vegeta would definately rock

Those would be cool but doubtful nintendo even considered them
