Switch Ships 122.55 Million Units as of December 2022

I'm waiting to update my Switch sales prediction until early autumn or the announcement of Switch 2. Whatever comes first, I'll update it.
If Switch 2 comes out in March 2024, 144 million seems pretty likely (even if a little lowballing). But if Switch 2 isn't out until Q4 2024 or later, Switch will probably sell at least 150 million lifetime. Switch will still have a little in the tank after its successor launches and won't be discontinued right away.
After the Wii U's failure, I was skeptical of how Switch would perform. I remember for years thinking that the best it would probably do were 3DS numbers. With its massive success, Nintendo is in very unsure waters with how the next platform could perform. The realistic best scenario is a drop from Switch, but still a large success and high profits. But a failure (like the Wii U) or an underperformer (N64, 3DS) is possible. I know the 3DS still sold 75.94 million units, but that's a little less than half of the DS. Nintendo was probably shooting for 95-125 million units with the 3DS. Expecting it to get really close to or exceed the DS would be folly.
