I personally don't want amiibos getting involved at all. If they were working with Nintendo then sure, but they are not owned by Nintendo. People seem to forget that, and are treating it as if it were a Nintendo game. It's not a Nintendo game though, it's a Playtonic game.
Since it has been confirmed on all consoles it seems extremely unlikely that there would be any amiibo related features (which I think is a good thing). I would also be skeptical about Playtonic making their own equivalent of amiibo, but this also seems unlikely as they would need a reader that worked with all consoles (like the Skylanders portal, which uses the USB port), and that just seems like a waste of resources, since it isn't a requirement for the game.
