In case you were wondering whether the definitive edition of Hyrule Warriors would be updated for the newer Zelda amiibos, Nintendo has your answer.
The Japanese website for Hyrule Warriors: Definitive Edition on Switch indicates that Breath of the Wild amiibo will be supported – namely Archer Link, Horseback Link, and Zelda. If any of the Champion amiibos are also supported, they are not listed on the website, though it is possible other Zelda amiibos function much the way they did in the Wii U game by offering more weapon drops than normal amiibo.
It’s like the three listed on the site get you the Link and Zelda Breath of the Wild costumes teased in the original trailer. The original game on Wii U had weapons (like Twilight Princess’ Spinner) that could only be unlocked with the appropriate amiibo, so it still remains a question whether the Breath of the Wild costumes and amiibo weapons will be similarly locked in the Switch version.

I really hope the amiibo aren’t the only way to get the costumes, and likewise that the previously locked items are freely available in the definitive version.
