Sounds about right.  Plus scalpers who were not Nintendo fans but snapped up as many as possible to sell them for ridiculous profit. 

The Smash Bros line is old news. Nintendo has made their strategy with amiibo pretty clear: support them for about a year, then replace them with a shiny new model. Oh sure, if you bought the Smash Bros or the Super Mario 'Mario' amiibo, so you get the full functionality in a handfull of Wii U games, but you'll have to buy this new 8-bit Mario amiibo to get the special Super Mario Maker content. Thanks for buying both Link amiibo, you'll be excited to learn that you can scan that to get a few arrows in Twilight Princess HD. PS we've made content for Zelda Wii U that can only be accessed with the use of this new Link amiibo, please buy him again.

Nintendo doesn't care about the Smash line of amiibo any more, and they don't want anyone else to care about them, either. Please look forward to buying our Pokken Fighters line of amiibo including Pikachu #2, Charizard #2, Mewtwo #2, and Lucario #2; our Star Fox Zero line including Fox #2 and Falco #2; our Zelda Wii U line including Link #3 and Zelda #2; and our Mario NX line including Luigi #3, Peach #3, Toad #2, Bowser #4, Yoshi #7, and Mario #8.

The problem is outside of collecting them they don't do much. The smash line sold well because people wanted to collect them, but nobody really wants to collect the animal crossing ones.
If nx doesn't have an amiibo skylanders game at/around launch then nintendo is stupid. You can sell whatever figure you want if they have a purpose, and platformer/adventure game like skylanders is a very good purpose

I already got all the Amiibo I wanted. Plus I looked back at my collection and realized I bought many that I really didn't need to (Pac-Man, Silver Mario, etc.). I'll get Wolf Link for sure, and Bayonetta I guess just because that's freaking hilarious, but probably no others. Unless of course Nintendo makes a game that has cool functionality for them.

nope i gave up and sold all of mine once they because readily available

I care about Amiibos as much as I did the moment they got announced.

yes they are made out of plastic, the plastic and chips are made out of the same maeterial Oil

I want it to be a fad, that goes away fast.

anything that sells well always appears over stocked. think about any popular normal thing you buy at a store. they constantly are restocking the item and making sure its available BECAUSE of the demand

like go into a store and look in the video game section- they'll always have all of the PS4 games available despite it selling well. same thing can be said for popular foods and other things

generally things only run out during extremely busy holiday time

I have no doubt Amiibos sold well during the holidays but to expect the shelves to be empty towards the end of January in stores is just strange. if anything stores have been restocked at this point

the only ones I want are the 3 pack splatoon, and that's so I can achieve/unlock everything in game with my ocd having self.
