Trivia

 * Another term used in Pokémon GO players community to describe Pokémon groups from each region is Generations. This term was adopted by community but it is not correct in context of Pokémon GO game as the game itself does not have generations as a result of being under ongoing development. This term wasn't officially referred in game nor by its creators on official social-media and information channels.
 * Therefore Kanto is Generation I, Johto is Generation II, Hoenn is Generation III and so on.
 * More about generations is available here.
 * Common thing for Pokémon, that were not available with main release of Kanto- and Johto-region Pokémon, is that those Pokémon either were legendary and/or mythical or have certain, special moves like Ditto, Delibird or Smeargle.
 * Pokémon from Hoenn region although didn't have their main release as they were released in smaller groups.
 * There has been Pokémon species from Hoenn added to game code since update 0.71.0.
 * Taking into account, that new Pokémon are released in the game every 6-8 month, Pokémon from Sinnoh region might be released on the anniversary of the game.
 * On December, 2017 in Apple Watch Store, Pokémon GO banner with Starter Pokémon from Hoenn region appeared- spoiling official announcement about release of Hoenn-region Pokémon that happened next day.
 * Release of fifty Pokémon from Hoenn region and Weather feature had trailer with similar cinematic style as trailer for release of Legendary Pokémon in raid battles and new gyms system and trailer of the game itself.
 * There are at most sixteen known regions that have appeared in the various Pokémon canons.
