Buuuuuuut an anonymous source has stated the following:
Nintendo will launch a website accessible from any web browser that will handle configuration of your Nintendo Network account for use on the Wii U or 3DS. He also stated that Nintendo Network will include many new features that haven’t been used before by Nintendo. According to his accounts: Nintendo Network = Sony PSN = Xbox Live.
Its REALLY hard to believe something like this... but the individual who submitted this to everyone wished to remain anonymous. Personally I don't think it can be compared to PSN and Live. It's much more believable that this has something to do with DLC. Only time can tell. What is everyone's thoughts on this? comment here or on the Facebook page.
