>>35378415>why a game not specifically about pokemonBecause every new Smash game has had new pokemon in it. Melee had Pichu & Mewtwo, Brawl had Lucario and the Pkmn Trainer, the last game had Charizard & Greninja.
Pokemon has probably gotten more representation in Smash than any other non-Mario franchise, so odds are there'll be at least one new playable pokemon character in the next game.
There's already been a standalone fire and water starter so some people think the next character could be a grass starter. People used to (or still do, I dunno) speculate the same thing with Sceptile.
All of this is just me making assumptions while I take a shit so take it for what you will, I haven't played Smash in years.
