I think an Amiibo hub game still has to happen next year though.
Those amiibo figures are going to start to collect dust on storeshelves and only Nintendo fanatics are going to buy the more obscure/rare ones, leaving piles of unsold Marios/Links/DKs everywhere if Smash Brothers is the only game that really uses it in a big way.
Like yeah I know it does some extra stuff in Mario Kart and Hyrule Warriors, but that just isn't good enough of an idea to keep these things selling. They need something far bigger to get kids coming back to buy more of them.
There's also a problem of like what does a Samus amiibo do in Captain Toad? Or Mario Party? Or Wii Fit Trainer? Or Marth? Or Fox? Sure Link/Mario work in other games, but a lot of their figures don't do anything but interface in Smash as a non playble character that's kinda pointless after they level up to 50.
Right now with amiibo unless you're a collector, there's really no big reason to own more than one or two at most. But kids love multiple Skylanders because gaining a completely new character in the main game is a big deal.
