It's just after 1 am. After some struggling, I finally make it inside the Nintendo e-shop. I find my way to the X&Y section. The Pokemon Bank is there. It's waiting for me. But it's not available yet. The release date has been moved from today into "to be decided" limbo.
Hopefully I don't break anyone's heart by sharing this, but Pokemon are just individual files. Very, very small files. Between 232 and 260 bytes, and even smaller before X&Y. So it should tell you something when the sheer force of the Pokemon being uploaded from Japan managed to knock down the 3DS and Wii-U e-shops. You won't find the Bank on the Japanese e-shop anymore; Nintendo has had it removed while they try to bring the servers up to capacity.
The Pokemon Bank and the Pokemon Transporter are the only way to move Pokemon from Generation 5 games (Black and White/Black 2 and White 2,) to Generation 6 games, (X and Y.) The two services were released in Japan Christmas day, with an international release scheduled for the 27th. For most of Europe, that's today. But it doesn't look like we'll be getting anything today. Maybe not for a while either, judging from the fact that the Bank's e-shop page has the release date listed as "TBD."
We'll hopefully hear news from Nintendo as the hours go by. Update: Nintendo has a response on it's help page.
Nintendo and The Pokémon Company International have postponed the launch of Pokémon Bank and Poké Transporter - two software applications that were originally scheduled to launch for Nintendo 3DS on Dec. 27 - due to a large volume of traffic to the Nintendo Network service. Due to the high traffic, players are having trouble setting up Nintendo Network IDs and downloading content in the Nintendo eShop on both Wii U and Nintendo 3DS. We truly regret the inconvenience, and wish to reassure everyone that providing a solution is our top priority. We apologize for the delay and thank you for your continued patience.
Happy New Year to you too, Nintendo.
