Nintendo of America announced that its 3DS and Wii U eShop will be down for maintenance starting at 9 a.m. Pacific Time this morning, and extending through 8 p.m. PST tonight.

The maintenance will likely lay the groundwork for an upcoming system update that will combine Wii U and 3DS account balances with a user-created Nintendo Network ID.

Purchases and other downloads will not be available during the maintenance period. You might want to use this opportunity to reflect on the good times you've had with the eShop, to better your relationship with the service in the future. Putting together a wishlist of eShop purchases might also help to pass the time -- may we suggest starting with the Sega 3D Classics series?
