I think with Pokemon and Smash coming out this year, 20 million is realistic. I suspect that Nintendo's prediction for 20 million was predicated on Labo which was a hige miscalculation. On the other hand, if you look at Amazon, you'll see the most wanted list is dominated by Nintendo (outside of cards and controller). Pokemon Lets Go topped it from its announcement. There is also the real possibility of more third party games such as Fortnite coming to Switch which will certainly help. So I think Nintendo will at least meet 20 million but wont exceed it by much more.
