"With this app, once you tap your amiibo on the NFC area of the GamePad, you will be able to play highlighted scenes of one certain title for NES or Super NES. You cannot play the entire game due to a time limit, but another tap of the amiibo will enable you to try another highlighted scene in the game. We hope that when you tap your amiibo, the quickly changing game scenes will pleasantly surprise you and make you feel as though you have just exchanged a game cartridge."
Bring that app to 3DS too, please! Nintendo also discussed sales rankings for amiibo in each region, potentially making more figures for particular amiibo that sell out shortly after launch, producing amiibo cards, and regional shipment breakdowns — read that part of the presentation here.
