"Nintendo's new game console is scheduled to enter mass production at the end of the first quarter 2016 and despite the fact that the Japan-based company is targeting to ship 20 million units in 2016, the device's upstream component suppliers expect shipments to only reach around 10-12 million units. The new console is estimated to enter mass shipments in the second quarter."
Note: Digitimes is a well respected publication, but they publish both factual and rumor type stories. This is clearly a RUMOR story.

Production volumes of NX in second quarter 2016 would allow Nintendo to stockpile enough units for a Fall or Holiday 2016 launch, so at least from the hardware side things look to be on track. The bigger challenge for Nintendo will be getting the OS and games ready for launch. If, as many suspect, NX has a new architecture vs. Wii/Wii U then the software will be a significant challenge and probably the gating item for product launch.
