Amiibos have generally been on a downturn in the economy when you consider that their most useful functionality has basically been neglected. If a Smash port comes around, then I believe that will reinvigorate amiibo relevance. After all, amiibo derived from Smash and without Smash amiibo don't have much of a purpose unless Nintendo can find another way to implement amiibo without making them lock content.
