This must be really confusing to many people because implementing a unique account system must be outside Nintendo’s capabilities, considering how primitive they usually are when it comes to technology.
A Nintendo customer service executive named David Marshall has outed that a unified eShop account system will be headed to the Wii U later this year and the 3DS will be patched to support it as well.
If your system gets stolen, your account can be transferred to a new system after intimating Nintendo customer service.
“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,”
“Of course, you asked this question because of the upcoming launch of New Super Mario Bros. 2 in retail and digital formats. What you need to know is that the digital format will only be available in the United States and Canada. We have nothing to announce regarding Latin American availability.”
