Nintendo will be using their NFC tech for their Pokemon U game. This will be a HUGE money maker for Nintendo. From what I understand, the way it will work is you get a little Pokemon figurine with a chip inside, which the Wii U detects and allows you to play that character in the game. With the amount of people who love this game and collect the Pokemon cards, I can't see how this won't be a massive cash cow for Nintendo. There will be hundreds of characters to collect, and correct me if I'm wrong, but even if someone homebrews the Wii U and pirates the game, they'll still have to buy the actual figurines to use them in the game. If this is true, Nintendo could give away the game for free and still make a killing on selling Pokemon characters.
They should make the figures like the Kid Robot style vinyl figures... including packaging them in blind boxes. This would make them super collectible and lead to more sales from gamers and collectors.
