Supposedly these characters were leaked through early scans (NOTE: NOT CHARACTER ROSTER, JUST NEWCOMERS). They are of course not definite even if this is legit, because the game is still in its planning stage. They include:
King K Rool (Donkey Kong)
Little Mac (Punch Out)
Saki Amamiya (Sin and Punishment)
King Hippo (Punch Out)
Prince Sable (Frogs the Bell Tolls)
Palutena (Kid Icarus)
Professor Layton (Professor Layton)
Crystal (Star Fox)
Slime (Dragon Quest)
My Opinion on some of the characters:
Zoroark- Lucario replacement ): Likely
Ghirahim- Too "one time only" ? But i hear he's very important to the whole Hyrule mythos.
LIttle Mac- Assist Trophy earlier, so seems okay.
Ridley- If they scale him down like in Melee's opening, it would work. Metroid needs a non-Samus representative
Palutena- PLEASE! She was a boss, so they have her moveset roughly. Hey, they made Peach out of nothing. I'd expect Magnus though...
Megaman- Not personal to me, but since people have been clamoring for him, I say okay.
Crystal- A non-Fox clone. Please.
Slime- lol, but it'd work. DQ Adventures for the DS gives him more viability, although I would prefer Sora and Riku as SE representatives.
