In addition to the many new Pokemon announcements, The Pokemon Company also said a new “core RPG” is coming to the Switch in 2019:

Finally, Mr. Masuda returned to the stage to give us a tease at the next major project in development. While Pokémon Quest and Pokémon: Let’s Go, Pikachu!and Pokémon: Let’s Go, Eevee! represent new and different play styles, he let fans know that a new Pokémon core RPG, developed by GAME FREAK, is planned for launch on Nintendo Switch in late 2019!

Looks like the Switch will be getting plenty of Pokemon games this year and next!
