The Pokémon Global Link, an online system supporting online tournaments, ranked play, and cloud saves, is to be withdrawn in February 2020, reducing the feature set of Pokémon Sun and Moon and Pokémon Ultra Sun and Ultra Moon on Nintendo 3DS after the launch of Pokémon Sword and Shield on the Nintendo Switch.
Now that Pokémon Sword and Shield have launched, the near-identical pairing together have become Nintendo Switch's fastest-selling title in the process, The Pokémon Company is drawing in some of the features supporting older games Pokémon Sun and Moon (2016) and their expanded successors Pokémon Ultra Sun and Ultra Moon (2017).
