Switch had a very slight adjustment down for previous weeks after the shipments (only 30k).
Current 2021 Sales: 16,665,724
2020 Sales Aligned: 18,171,135
So 2021 is down YoY by 8.3% and 1,505,411 units.
If it remains 8.3% down by the end of the year 2021 sales would be 25.86m
It would need to outperform 2020 in Nov/Dec to finish with above 26.6m.
