Pokémon Sun and Moon for 3DS will be joined by Pokémon Stars for Switch.

Multiple sources tell Eurogamer the game is already well into development, will launch in 2017, and currently holds the codename of Pokémon Stars.

Earlier generations of Pokémon games have featured a third title launched later with expanded features – Pokémon Yellow followed Game Boy originals Red and Blue to start this trend, which continued through until Pokémon Platinum followed Diamond and Pearl on DS.
