While Xbox 360's Gamertag and PlayStation Network's PSN ID systems have allowed unique online identifiers for some time, Nintendo's 3DS, Wii and DS have lagged behind in the online space. Speaking to investors, president Satoru Iwata revealed Wii U will get individual user accounts for online services.
Also for the Wii U, we are planning to introduce a personal account system compatible with Nintendo Network. With this, for example, the ease of using a video game system when the hardware is shared by multiple family members, which has been a challenge we needed to tackle, shall be improved, and we will also be able to construct and offer the system by combining a variety of different services and content.
Here's hoping this means digital purchases will be linked to the user account instead of the console, as is currently the case.
