Nintendo is apparently tired of not having a uniform login solution across all of its handheld and home console devices and has decided to do something about it. According to this Polygon report (citing a report from Nintendo World Online), Nintendo customer service representative David Marshall has confirmed that the company will implement a unified eShop account system for Wii U and 3DS. The change to the system will go live at about the same time that the Wii U launches, according to the report.
"A unified account system will be implemented later this year with the launch of the Wii U. Eventually this same account system will be made compatible with Nintendo 3DS systems. At this time we have no additional details to offer and nothing to indicate how or if this will work outside the United States and Canada. In the meantime, if the system has a problem, taking it to an Authorized Service Center will maintain the Nintendo eShop account. If the system is stolen, we can transfer the account to a new system once we are provided with a valid police report."
Besides simplifying the login process and allowing users to store payment information, the new system could hypothetically allow users to move content across devices much like they can with Sony's various devices using the PlayStation Network.
The Wii U is expected to release late this year, which means that you can expect this new unified account system to be deployed shortly thereafter across various Nintendo devices...
