And as for beating the DS, forget about it. The Switch's 2020 was an anomalous year, and shouldn't automatically be taken as any indication that it will set any sort of new records in terms of absolute numbers for post-Year 4 sales.
And it doesn't need to set any new records! It's doing perfectly fine. In fact, it's doing better than fine. It's doing great. It is absolutely no slight against the system if it sells "only", say, 42M instead of 47M or 50M or 55M.
The DS is currently the top seller in the US, but it's perfectly fine if the Switch outsells it. In fact the DS has done better than fine. It's done great. It is absolutely no slight against the system if the Switch outsells it.
