Pokémon Bank is a new service coming from Nintendo in that will enable you to store all your little pocket monsters (fnarr) in the cloud for a price.
What price? That we don't know. We do know from the Nintendo Direct (watch that below) however, that you will be able to store 3,000 Pokémon in the Cloud subject to paying an annual charge. What happens to your chaps if you don't keep paying is unknown - probably PokeDeath. Also, announcements of dates for Pokémon X and Y were announced: October 12th. Watch the show below.
