Sinnoh Confirmed is a long-running inside joke among Pokémon fans that originated during the years leading up to the official release of Pokémon Brilliant Diamond and Shining Pearl. Similar to the 'Half-Life 3 Confirmed' meme, players would take minuscule details from official trailers—such as the number of flowers in a field or a specific NPC's dialogue—and use convoluted logic to 'prove' that remakes of the fourth generation games were in development. Even after the remakes were actually released, the phrase persists as a satirical way to mock over-eager fan theories or to express excitement whenever the Sinnoh region is referenced in modern media. It perfectly captures the collective anticipation and eventual payoff of one of the most requested projects in the franchise's history.
