As you can see, Pikachu, Kirby, and Sanic are sticking out of their borders.
Now you may think this means nothing, but listen to this. Before the April Smash Direct, Pikachu was sticking out of his border. Then we got Charizard and Greninja.
Sonic was most likely hinting Pac-Man here, since they are both 3rd Parties.

Who do you think they'll be.
Personally, I'm going for Mewtwo and/or Jigglypuff for Pokémon, and Meta Knight (and MAYBE Bandana Dee, but I don't want to sound greedy for newcomers) for Kirby.
