When asked how much Nintendo’s Wii U online service will cost, Nintendo CEO Satoru Iwata said that while he doesn’t necessarily reject the idea of a paid service that allows not just Wii U but various other devices to connect to the Nintendo Network, considering Nintendo’s users, a paid membership service is not the best approach.
By having everyone use the Miiverse together, word of mouth will more easily spread. This will lead to greater hardware and software sales.
In short, Nintendo’s online will be free!
Of course, we’re still left in the dark in pretty much everything Nintendo has planned but at least you can take comfort in the fact that they’ll be offering free online gaming.
