Keep in mind that Nintendo denied new hardware at E3 2019 (June), announced Switch Lite at July 10th 2019 and released it 2 months later September 20th 2019.
The same with Switch OLED model. Announced July 6th and released 3 months later October 8th 2021.
So if we see a new model, it should be announced 2 or 3 months before the release. Zelda TOTK releases May 12th. So there could be an annoucement in February or March this year without a lot of rumors ahead.
If you mean a minor revision to the existing Switch then sure, that's possible (I'd still bet against it, given market and supply chain conditions). I thought we were talking about a Switch successor.
