Somwhere between 15 and 20 million. And Nintendos next home console will come between late 2017 and end of 2018.
There's tons of ifs. If MK8 had come earlier this year, SSBU had arrived before the 3DS episode and XCX had come out in Japan before the end of the year Nintendo would have sold over 10M until end of this year, espacially with a price cut.
Now it's the same for next year. With Zelda and other games coming in time and with a price cut, Wii U could still improve. With some delays and no price cut it wont.
