Alleged leak saying Snakemen are confirmed to come to Origins for 2023. But I think that was a given with all the new reveals we saw, particularly with that blury Kobra Khan we image we saw, which Matte hasn't officially revealed as of yet.

Wouldn't be surprised if King Hiss is out around the same time as a deluxe while the other 3 are regular releases. They'll probably finish out remaking the vintage figures next year and have room to do branch out: More 200X, Filmation, repaints, or characters that never got made. We've also still yet to see official reveals for the movie figures that were in a few leaks within the past year. I'd imagine those appear next year as well when they knock out Saurod, Blade, and Gwildor.
