Oook trovato la comunicazione ufficiale Nintendo
As it stands, even after the store officially closes,
Wii users will be able download any past titles they’ve purchased and downloaded from the Wii Shop Channel, provided they can fit them on either the Wii’s internal storage or an additional SD card. However, Nintendo said that in a
yet unknown point in the future, the company will close all services relating to the Wii Shop Channel, "including the ability to redownload WiiWare and Virtual Console games, as well as the Wii System Transfer Tool, which transfers data from Wii to the Wii U system."
By shutting down the Wii Store Channel and not letting users download old games, Nintendo is once again showing that in the modern digital era, you don’t actually own the things you buy.

In un futuro (non chiaro) rimuoveranno tale funzione.
