For Switch 2 i think the fact that it was readily available all year means that it didn't get a strong holiday boost, most people interested in buying Switch 2 year 1 already got it during previous months, and families are likely not that interested in Switch 2 due to the price as well which also lowers its holiday boost.
Switch 2 does not have the same amount of people in the US and Europe that view it as a must have item compared to Japan, which is why Switch 2 demand is higher in Japan even though their economic situation is worse than it is in western countries. In the US and Europe, Switch 2 is easily skippable this year while in Japan its seen as something worth to use some savings to get this holiday.
