When Amiibo launches there will be close to 10 million potential customers, every Wii U owner has the NFC reader via the Wii U gamepad, and a high percentage will have at least one of the games that Amiibo is compatable with, even existing games like Pikmin 3 or something like that could have Amiibo support patched in. The possibilities are endless, if marketed correctly Nintendo could do well out of this.
