-A lot of Zelda DLC for other Nintendo games, like Tomodachi Life, Mario Maker, Splatoon, Xenoblade X...
-Some free Zelda games, maybe they re-release that Four Swords downloadable game on the 3DS.
-Probably some physical goods on the new Nintendo Club.
-Zelda U.
Although I would rather enjoy the Pokemon anniversary, or something for Metroid (how many Metroid anniversaries have been ignored already?).
