According to the leak, the first expansion of the Pokémon trading card game Pocket will be released at the end of January

According to a new leak, hit smartphone app Pokémon TCG Pocket will add its first major expansion with new cards at the end of January.

A datamine of the game's event schedule published by Centro Leaks suggests that the game's currently unnamed first expansion will launch on January 29th – with the caveat that final dates are still subject to change.

This current plan would mean there's a window of about three months between the release of the Pocket Pokémon Trading Card Game and the arrival of a flood of new cards – which feels about right?

However, there is also evidence of a special booster pack set to launch in December – suggesting a few additional cards will arrive a little early to surprise fans.

Other upcoming additions to the Pokémon Trading Card Game Pocket discovered in the datamine include a new card rarity and the addition of rare picks to the Wonder Pick mechanic.

Pokémon TCG Pocket appears to be off to a great start, with the game earning $12 million in its first four days and more than 30 million downloads after a week.

Pokémon TCG Pocket is heavily focused on opening trading card game packs, but you can also play a simplified version of the classic trading card game through the app.

Last week, the Pokémon TCG Pocket launched its Genetic Apex Emblem Event, which added new missions and a few rewards. Do you want to move forward? Here is our Pokémon TCG pocket tier list of the best Pokémon cards, trainer cards, rental decks, and decks.
