Future Update Plans

To all of you playing Pokémon Trading Card Game Pocket,
This is the Pokémon Trading Card Game Pocket Operations Team. First off, we would like to use this opportunity to thank everyone who waited in anticipation of the release, as well as everyone who has given the game a try. We are continuing to develop and operate the game so that everyone can enjoy it even more, and we plan to hold a variety of in-game events in Pokémon Trading Card Game Pocket going forward.

Now then, today we would like to announce new content planned to be released in a future major update.

To begin with, we plan to add new booster packs by the end of the year. In addition, we are aiming to add a feature that allows certain cards to be traded starting in January, 2025. We are planning to gradually expand the selection of cards that are able to be traded.

Also, we have other new features in development outside of the trade feature introduced here. We plan to announce more details about the update as the dates for the addition of these features are finalized, so please look forward to it.
