That can be true for the last couple months perhaps. But Series S been readily available in a lot of places for several months now, and during the same period we had like Japan numbers and some other places showing 1/3 of the Series shipped were series S.
As I live in the US, that is the country I am speaking for. I cannot comment outside of that, as I like to go off of 1st hand experiences. And the case here is that there are more Series S consoles in circulation than the PS5 and XSX, as both of them are sold out but the Series S is selling more despite being available on store shelves. There can only be one explaination for that, and lack of appeal isn't it.
