Sony have botched in a few markets before and they are mostly seen as the corp that panders to teens/adults, I frankly don't see them ever trying to do a Nintendo and appeal to kids let alone go with their own Amiibos.
Sony is doing what they know they are good at and the market they are in, there's no need to try emulating what someone else already started first and is already good at.
I also don't get why you want Sony to steal everyone else's thunder, they don't need Amiibos to be good and they don't need to crush Nitnendo and their fans so it seems foolish to desire such a thing.
Mankind, in its arrogance and self-delusion, must believe they are the mirrors to God in both their image and their power. If something shatters that mirror, then it must be totally destroyed.
