So based on what I've been seeing, the regular Switch model is now becoming more and more readily available for purchase. Before you'd literally needed to wait the as soon as stores received the Switch in stock to be able to get one, but now you could nearly easily get a 300$ Switch whenever you want.
This could either mean that Switch demand is now finally starting to decline to levels where more Switch's will be available to purchase now in 2021, or that Nintendo has ramped up production even more the past few months to get the Switch more readily available. I'm leaning more towards the first option since I doubt Nintendo a year after AC and the pandemic Nintendo finally decided to ramp up production to meet all demand, plus I don't think Nintendo is really able to produce enough Switch's to do this. Nintendo last year could've easily broken the DS's record in sales if there was more stock but it seems like Nintendo could only produce so many Switch's as it seems like 30Million in one year is maximum capacity for them. So I'm leaning more towards a decline in demand now.
