The Nintendo Switch is both the new nintendo handheld and console.
The 3DS sold 61.6 million.
The Wii U sold 13.6 million.
Of the 3DS userbase, let's say only 25 million decide they want the next Nintendo handheld.
Of the Wii U userbase, let's say only 6 million decide they want the next Nintendo console.
And let's say of all of those that 10 million would have bought both the handheld and console seperately if it was the same situation as 3DS and Wii U, but now they just have to buy one single system since the Switch is both.
That's already 41 million.
The Switch will have Pokemon, Yokai Watch, Monster Hunter, Dragon Quest, Mario, Zelda, etc, etc. All of which could get the Switch to and PAST 20 million just by themselves.
So yes, I imagine the Switch will easily surpass 20 million.
