Did you not read the Link?
Manga/anime characters will NEVER be in a smash bros game.
Manga characters will not be featured in Brawl =/= Manga characters will never be in Smash in the future.
Not saying it's likely to happen at this point (it wouldn't be a possibility until at least after this pair of games by what I see), and while Sakurai
has brought up as early as the original Smash that characters outside of gaming media such as James Bond and Popeye (both being examples from
Nintendo games) have licensing costs that aren't worth the hassle, he
did say the same thing about non-Nintendo gaming characters as well, and we've had three of those so far.
EDIT: My point is, there will eventually be a time when "GOKU IN SMASH BROS.!" could be more than a fanboy's dream, just like what happened with "SONIC IN SMASH BROS.!".
