The Zelda amiibos releasing on 12/2 have no specific usage right now confirmed for any game. Unless an older game is getting an update, and judging by how we haven't seen the back of the box on any of them, they'd have to have some sort of announced use in Breath of the Wild, no? Why else would anyone buy them? It'd be terrible advertising, I'd think.
