This is a milestone. But I don't think we expect Switch to be reaching any hugely impressive milestone when it's been out less than 3 years in the market. Maybe outselling XB1 (worldwide) will be impressive when it happens. That is about it. Give the Switch a few more years, and then it will be hitting the truly impressive milestones.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
