Time will tell on all that but I highly doubt and wouldn't hold my breath on any Nintendo + Disney partnership. It's a dream to say Amiibo + Disney Infinity is in our future based on a movie cameo. It doesn't seem like Nintendo has any interest in partnering with Disney or Skylanders, or any other established series that uses the NFC. It's not the same thing as the others at this point and I can't see them steering this ship toward being a complete copycat. It might be beneficial for Nintendo to get Amiibo in Disney Infinity but that kind of would steer the focus away from Disney Infinity and turn it into Nintendo Infinity. It would probably just end up being costumes or small DLC like the rest. Not to mention they're not in the Disney universe at all except for Wreck it Ralph so what would their purpose even be? "Amiibo Infinity" prob will have to wait some time.
