Not to worry, though: even after late March 2023, and for the foreseeable future, it will still be possible to redownload games and DLC, receive software updates and participate in online play on Wii U and the Nintendo 3DS family of systems.
This means that on May 23, 2022, it will no longer be possible to use a credit card to add funds to an account in Nintendo eShop on Wii U or the Nintendo 3DS family of systems.
Nintendo has announced that in a year’s time, the firm will be shutting down the Nintendo eShop for the Wii U system and the Nintendo 3DS family of systems.
Users who link their Nintendo Network ID wallet, which was used with Wii U and 3DS, with their Nintendo Account wallet – used with Switch – can use the shared balance to purchase content on any of these systems until late March 2023.
