During its Pokémon Presents broadcast, The Pokémon Company teased a couple of new games coming to the Nintendo Switch later this year. Pokémon Scarlet and Violet will launch on the portable console in late 2022. And you can see the teaser trailer above. As The Verge pointed out, this "open-world adventure" looks reminiscent of 2019's Pokémon Sword and Shield. According to Game Freak, they "take a new evolutionary step in the Pokémon main series."
Here's the official description:
Trainers can explore an open world where various towns with no borders blend seamlessly into the wilderness. Pokémon can be seen everywhere in this wide-open world — in the skies, in the sea, and on the streets.
As one of the main characters, trainers will jump into the world of Pokémon Scarlet and Pokémon Violet to begin their adventure, where they will have a different outfit depending on which game they are playing. Trainers will then choose either Sprigatito, the grass cat pokémon, Fuecoco, the fire croc pokémon, or Quaxly, the duckling pokémon to be their first partner pokémon before setting off on their journey.
