Junichi Masuda Tweet - January 11th, 2014

お待たせしているポケモンバンクですが、制作した私たちも皆様にお届けすることができず、大変心苦しく思っています。任天堂さんの公式発表をお待ちください。

I'm very sorry, but while we know you're all waiting for Pokémon Bank, we the developers are not the ones who deal with its distribution. Please wait for official announcements from Nintendo.

Nintendo of America Tweet - January 10th, 2014

More information on the launch of @Pokemon Bank and Poké Transporter will be announced in the future. Thanks for your patience!
