This first wave has taught me to think a bit differently about how Nintendo's approaching the amiibos. I think everyone expected them to treat it like a widespread toy release with a vast overestimated appeal. But while I think that may be the case for the recognizable figures, the Marios, Pikachus, Links, etc, any character that won't be recognized by children is likely not going to see a large release. It makes sense when thinking about people outside the collecting/hardcore fan group, and I'm wondering if Nintendo's going to adjust their numbers or keep making certain figures in low quantities just for the sake of having some be rare (which isn't too uncommon in the world of collectable figures).
Of course, this all could be a devious plot to inflate preorder numbers, since the tiny amount of Marth, WFT, and Villager amiibos is likely going to make collectors over paranoid. I'm willing to bet that preorders for the next wave are much higher than they were for the first. Who knows.
My policy is as follows: Any fire emblem, obscure, new, or retail exclusive character is going to be mandatory preorder, everything else can probably be left to a later time. I learned my lesson after that $27 Marth off of ebay, though even that's a steal compared to what it goes for now.
I feel like an 8 year old obsessed with Pokemon cards all over again. This is going to be the death of me.
