And then there is Ryng Tolu who predicted 15 million for the first year in January 2017.
your future prediction will look pretty silly though ;) was too bullish when there are no signs of sales exploding.
Sure there are.
1. Has yet to recieve a price cut, $199 in 2019 could be huge.
2. Their biggest IP, Pokemon, Animal Crossing, Smash Bros, 2D Mario, have yet to release.
3. Nintendo Labo looks like it could be the next huge kid/family/casual hit.
20+ million in 2018 & 2019 each is very possible which would put it around your lifetime number in just 3 years.
