As of June 30th 2024, Pokémon Scarlet & Violet has sold 25.29 million units, making it the third and fastest Pokémon game to ever hit the 25 million milestone. Only one million behind Sword & Shield (and with no other Pokémon games until 2025) it's sure to surpass it and become the second best selling Pokémon game ever. Taking into account individual version games sell less and how Scarlet & Violet is the only true core Pokémon experience until at least 2026 (30th anniversary) I wouldn't be surprised if it gets close to Pokémon Red, Green & Blue sales.
