After getting rocked by high traffic volume on Christmas Day, the Nintendo eShop will undergo 12 hours of maintenance today from 1 PM to 1 AM PST.

Nintendo 3DS owners can finally share their eShop account balance with their Wii U, as the promised system update adding Nintendo Network ID support has arrived today. The update also brings the Miiverse social network to 3DS, to chat about games and share pictures.
