Looks like there might be some more 30th anniversary Zelda amiibo on the way. Dataminers have been pouring through The Legend of Zelda: Breath of the Wild, and they've uncovered a list of all the amiibo the game uses. The thing is, the list contains three lines for amiibo that don't exist.
Again, this information is found right alongside the listings for all the other amiibo. Looks like there could be more on the way!
