Details about the membership service replacing Club Nintendo were announced today at the briefing by Nintendo President Satoru Iwata. The service will be a product of the partnership between Nintendo and DeNA:
"Nintendo, together with DeNA, will jointly develop a new membership service which encompasses the existing Nintendo 3DS and Wii U systems, the new hardware system with a brand-new concept, NX, and smart devices and PCs, and Nintendo will be the primary party to operate this new membership service. Unlike the Club Nintendo membership service that Nintendo has been operating, the new membership service will include multiple devices and create a connection between Nintendo and each individual consumer regardless of the device the consumer uses. This membership will form one of the core elements of the new Nintendo platform that I just mentioned."
