On the Minecraft x Super Smash Bros Direct that took place last night, Sakurai confirmed that Amiibo for Banjo-Kazooie, Byleth and Terry were all on the way for 2020.
Sakurai said that these were prototypes, so it’s unclear if these will look 100% like the final form, but I’ll take any Banj-Kazooie Amiibo that I can get my hands on.
