>>35407902>M21 is starring a Gen 7 Pokémon, while the final movie (or movies) of a generation always star a Pokémon of the next gen.There's still a chance that they can reveal a Gen 8 Pokemon for the movie before the movie hits theaters, if it isn't in the movie there's the possibility of it being in the movie short or even one of the last episodes of the anime. Hell the Genesect movie was the last for Gen 5 and didn't include a Gen 6 Pokemon in the movie (just a mechanic for X and Y) but did include Sylveon in the short, also Alexa showed up in the anime with Helioptile, Noivern, and Gogoat.
