"Pokémon GO Tour: Sinnoh Unveils Exclusive Spaces for Arceus and Manaphy Debut"
Pokémon Go Tour: Sinnoh will not include Arceus, Manaphy, or Phione despite being some of the only Gen IV Pokémon missing from the game. Niantic aims to give these Pokémon a dedicated space for their debut outside of the event, focusing instead on featuring Origin Forme Dialga and Origin Forme Palkia. This decision aligns with the company's strategy of spacing out new Pokémon releases across different events, leaving the possibility of seeing these highly anticipated Pokémon in future events.
