I have seen a ton of posts on here about all sorts of different games at E3 and if they will or will not make a sales impact but the one thing that I have no doubt in my mind is going to be a massive seller is the one thing that people are ignoring. Amiibo just completely leveled the playing field when it comes to 2014. Yes PS4 and Xbox One will have more multi-plats, but Nintendo just completely locked up the entire market of young gamers. These figures look awesome and when kids find out that they will be able to use them in games that they already love like Mario Kart and Smash Bros then they are going to be having ALOT of them on their Christmas Lists. Stack that with the fact that there will be plenty of older gamers this holiday season looking to buy a Wii U for Smash Bros, and some of the other great titles coming out and I really think that Nintendo has a real shot at dominating this holiday season.
I wanted to add to that I think the "Amiibo" name is brilliant. They are creating an entirely new brand that they can market and comercialize instead of just calling them something basic like Nintendo Trophies.
