It somewhat depends on how many Switches they are able to supply. I do think Nintendo will not supply enough Switches these holidays. Most likely, yes, Switch sales will pass last fiscal year's total by the end of 12/31/2019. If they don't then it will be because Nintendo severely underestimated demand for the Switch.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
My Bet With curl-6
