This allegedly includes the source code for Pokemon Platinum, source codes for Pokemon HeartGold and SoulSilver, beta builds of Pokemon Black and White 2, beta builds of Pokemon X and Y, and potential internal codenames for upcoming Pokemon projects. Within it are mentions of an online Pokemon game, a collaborative project between Game Freak and Studio ILCA, the potential code name of the Nintendo Switch 2 being "Ounce", and a project named Gaia, which may be the next generation of Pokemon titles.
Further details are slowly being posted on X, and as more becomes clear, we'll be sure to update this post with new information.
