Nintendo Switch has had one of the best selling dynamics in a long time. Why do some people still think that the console will not exceed 100M units sold? It is already at 66M units sold in 3 years and 9 months is huge, the PS4 had taken 3 years and 11 months to reach this score. The Switch is a primarily portable console and Nintendo are just unbeatable in and dominating this industry.
And where exactly do you meet these people? I think everyone on this forum these days believes the Swiitch will sell more than 100 million.
I still see Youtube videos saying stuff like, "Do you think Switch can outsell the Wii?" People on Youtube aren't necessarily following the data as closely as people on this site.
