Now, I do think Amiibos could have some interesting applications. For example, I always liked how Super Smash Brothers lets you basically use your Amiibo as a Pokemon. =P You fight against him, train him, customize him, etc, and can carry him around with you, ready to unleash him against your hapless foe's own Amiibo-stored warrior! =O I always figured that's what the Amiibo would be presented as, a means to store your own personal 'touch' on a particular game or character, that you could then share with your friends on other systems.
Less enamoured with it being used as a DLC gate, though, especially given we are talking about completely mundane, static DLC, not dynamic character info like with the Smash Bros example. It's just kind of the lazy route to take, in the same way pre-order-exclusive DLC is lazy; trying to add value to a product or concept by making it the only means to acquire the thing you ACTUALLY want.
It's pretty likely that the Amiibo is factoring into at least some of that price, especially since the digital version appears to be ten bucks cheaper. Even if the digital version was the same cost, though, it doesn't necessarily mean the statuette is 'free.' Like, you know when a company that sells furniture or the like offers 'Free Delivery!' where they have movers bring the thing to your house 'At No Extra Charge!' That's not actually the case. The costs associated with the delivery- gas, the driver, the movers, etc- have simply been folded into the cost of the furniture EVERYONE is buying, regardless of who does or doesn't want delivery. Now, this arrangement would likely benefit those who WANT delivery, (because since all customers are paying for delivery, the per-person costs are usually somewhat lower,) but those who choose to bring the thing home themselves do get shafted because they're still paying for some of that delivery they never bothered getting. =P
Now, given it's being bundled in with the game, the Amiibo's overall cost might be LOWER than if it were a standalone. This means those who WANT the Amiibo are benefited because they get their statuette, with the piece of DLC, for cheaper than they would have if they'd had to go out and buy it separately. Huzzah!
But that leaves those who don't want the statuette rather irate, because ultimately they're still paying for that thing they don't want. =P And there's no way to just pay for the value of the bonus dungeon itself; if you want that little bit of extra game content, you have to also pay for the materials and manufacturing of some statuette that, best case scenario, you MIGHT be able to re-sell online afterwards? I mean, if the selling point of the product is 'You don't actually have to KEEP the thing you bought!' that kind of suggests the product isn't terribly desirable in the first place. o.o
