No, I guarantee they will. You are forgetting Ike and dedede sold through tons of different stores, both online and offline. These will only be sold through one store offline.
Even still. They said before stores were getting at least 30. That alone put the first North American shipment at around 150,000, which is already a pretty insane number. On average each amiibo character has sold around 185,000 total in North America (based off of the total number of amiibos sold, and the latest released regional breakdowns), and you have to remember most characters have gotten at least
two shipments so far, and many have had several more like Link and Mario.
But now it seems like most stores are getting
40, and many more are getting well more than
that. I just don't see how, of all things, a three-pack of niche characters is going to have such a
gigantic initial shipment - one that seems on track to dwarf
life-to-date shipments for the majority of characters.
