In a Nintendo Direct presentation this morning, Nintendo, Game Freak and The Pokémon Company shared new details on Pokémon X and Pokémon Y—specifically, how you’ll be able to transfer your old Pokémon to the new games.
Nintendo will release a downloadable app for Nintendo 3DS titled Pokémon Bank. This application will allow you to store your Pokémon in a box that resides on the Internet. You’ll have access to 100 boxes, allowing you to store up to 3,000 Pokémon. You’ll be able to transfer Pokémon to and fro between Pokémon Bank and Pokémon X/Y.
Additionally, a second application called Poké Transporter will allow you to transfer Pokémon from Pokémon Black/White and Pokémon Black 2/White 2. If you put any of those four games in your Nintendo 3DS cartridge slot, you’ll be able to transfer Pokémon from them to Pokémon Bank. Then, using Pokémon Bank, you’ll be able to transfer those Pokémon into Pokémon X and Pokémon Y.
Pokémon Bank will require an annual fee. The storage service will be an ongoing service that will be continually maintained and will be compatible with Pokémon games developed in the future as well. More details regarding this service will be announced in the future.
