This may sound like a ridiculous idea, but what if future games would feature various cry updates for certain Pokemon? (I liked when they did Pikachu's for the games (except Pokemon Quest, Legends: Arceus, and Scarlet/Violet which used the Gen. 1 variation.)
It's possible they could do that, but honestly I prefer the cry Pikachu had in legends Arceus. I've never liked the whole Pokémon saying their name (even in the anime). Some Pokémon have really cool sounding cries. It was fine when it was just Pikachu and Eevee but I wouldn't want them to do many more than that.
