My guess is that once the numbers come out and they see that Amiibo does well for them, as it seems to be already that Nintendo is happy with their holiday sales, they could occasionally release figures that aren't any longer in production for a limited time. Or they'll just realize that the demand far exceeds what they thought and will simply increase the amount of figures produced in the next waves coming up. I'd love to see that with the hype of Lucario, Shulk, Meta Knight, and apparently Rosalina, we still end up finding the figures out on shelves when they release because they got more in than they thought. At least that's what I'm hoping for with Lucario.
