Knowing ninty i think it would be just be used for game saves and in-game downloadable content everything else would probably still be done via sd card...
What it needs to be is just like that image but it acts exactly like any other portable hardrive. (pretty much a big ass usb drive) it can be used to view videos,pics and music on the wii and also creates something to store extra vc/wiiware games on it and game saves.
