They don't want the money... yet.
Nintendo has delivered details about their online service, including the US$ price and the time to jump in.
The "Nintendo Online Service" will cost $19.99 US a year ($3.99 for one month, $7.99 for 3), and its release originally tabbed for fall 2017 has now been pushed to 2018. A free version of the lobby and voice chat app will be available this summer, and the "Classic Game Selection" was shown to include Super Mario Bros. 3, Dr. Mario and Balloon Fight. No mention was made of the previous one month timeframe for the games.
The service will also offer additional eShop special offers in the annual cost.
UPDATE: Kotaku has confirmed that the monthly special download has been removed.
