From Nintendo Everything: "After The Legend of Zelda: Skyward Sword was announced for Switch yesterday, it promptly went up the eShop for pre-order. It seems that the store listing has a bit of additional information about the game. As it turns out, amiibo support is listed as one of the included features.
Nintendo hasn’t yet said anything about plans for amiibo in Zelda: Skyward Sword HD, so fans will be left to speculate for the time being. At the very least, the Skyward Sword Link figure from 2017 should be supported."
