One of the biggest criticisms of 3DS was the lack of a digital store at launch. A store has since been set up and now, according to Nintendo, the firm will ditch its current separate shop system to implement a more user-friendly approach.
"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,"
Good news for WiiU/3DS Users!
