On the distribution artwork it seems that there is a Phanpy and Heracross, which were once Ash's Pokémon and it has become increasingly likely they will be Ash's other Pokémon. There is also a possibility they will be wild Pokémon or Pokémon owned by other Trainers, which things like that have been seen on previous distribution artworks and it may be the case for Staryu on the poster, who isn't seen to be owned by anyone on the main cast.
It would be lovely if those really are his.
One of my major complaints about M20 was that it was basically just Pikachu and Charizard, yes Butterfree was there.... but he left cause apparently they couldn't let it be an entirely AU where Butterfree stayed. It'd be boring if it was just Pikachu and Charizard.... again.
