9 Years and the switch 1 wasn't heading straight into a recession and hyper inflation and rode that massive 2020 lockdown sales spike.20 million is for Switch 2's first year with number would be higher as 2nd year, 3rd year, 4th year and goes on.
Switch 1 sold nearly 16 millions after first year.
As for your question, probably not for many years.
It took 9 years for Switch 1 to hit 156 millions.
Apparently their investors were actually upset with them that they only raised it to $500.9 Years and the switch 1 wasn't heading straight into a recession and hyper inflation and rode that massive 2020 lockdown sales spike.
While I have no doubt the Switch 2 will be successful given the shit show of global economics it will be tough for the switch 2 to outsell the switch 1. With how Ram continues to skyrocket in price who knows how long they can hang on to that $500 price point.
No, Nintendo didn't confuse ANYONE with the Wii/Wii U.*Nintendo confused its customers with Wii/WiiU. They are doing again with Switch/Switch2. Just wait and see.
