I think they are being brilliant about it. More and more amiibo's have sold. Most people that I know that have amiibo's are obsessed with collecting them (I myself have 5). Eventually, when the game launches, there will be so many people that look at their amiibo's and convince themselves that they want that game because of all their amiibos.
It's far easier to sell a game that people have all the parts for in advance than to sell a game before the parts come out or at the same time and then tell them they have to buy additional things to unlock the actual game. The prior makes it feel like an amazing deal (I already own those amiibos so all I need is the game!) but the second one makes it feel like I'm being robbed.
