Rumor Claims Pokémon Winds and Waves Could Introduce the Largest Pokédex in Series History

A new Pokémon Winds and Waves rumor suggests that the upcoming Generation 10 titles could feature the largest Pokédex the franchise has ever seen. According to information shared by multiple well-known Pokémon leakers, the games may include around 530 Pokémon, with more than 300 reportedly being brand-new species. The Pokémon Company and Game Freak have not confirmed these claims, so the information should be treated as an unverified rumor.

The leak claims that roughly 307 Pokédex slots in an internal build are currently reserved as placeholders for new Pokémon. If accurate, this would mark one of the biggest expansions in the franchise's history and the largest number of new creatures introduced in a single generation. Several prominent community insiders have stated that independent sources support the report, although no official evidence has been released.

Pokémon Winds and Waves was officially announced earlier this year as the first mainline Generation 10 games, scheduled to launch in 2027 exclusively for Nintendo Switch 2. So far, Game Freak has confirmed a new tropical region, open-world exploration, and three starter Pokémon, but has not revealed how many creatures will appear in the final Pokédex.

Until Game Freak shares additional details, the reported Pokédex size remains speculative. Even so, the possibility of introducing more than 300 new Pokémon has generated significant excitement among fans, who are eager to see whether the next generation will deliver the largest roster in the series' history.
