Reminder: That's shipped to suppliers, not consumers.
Some members of the supply chain may have begun floating shipment numbers for new Nintendo hardware to release in 2016.
According to the Taiwanese newspaper DigiTimes, the new system would enter production at the end of the 1st quarter of 2016 - whether fiscal (April - June) or calendar (January - March) is not specified - and would ship between 10 and 12 million units in the first year.
The sources also indicated that Chinese manufacturer Foxconn, most famous for developing the iPhone, has been tapped to manufacture the device but the company is not commenting. There is also no indication as to what form factor the products would take.
