Two characters from Wonderful 101? That's a bit too much for a game with only 1 game that isn't very popular yet. There are other cool first-party games like Golden Sun (3 games) and Xenoblade.

Also Sega and Nintendo are still separate companies so a 2nd character isn't possible right now. And this is just something personal, but I don't think we need another F-Zero character.
