I'm really not seeing anything that's causing the plastic production line to slow down.
2022: Horses, Bases, Spacenam, Boxers, Aztecs, Conquistadores, Cannon Fodder 2, Bulldogs, Goths, Panzer Lehr. The two WGA boxes from the 02 Hundred game sprues were not released in 2022 but you could get 02 Hundred - count that as a 2022 or 2023 one as you see fit.
2021: Italians, Lizardmen, Goblins, Cannon Fodder, WW1/2 French, Late Romans, PanzerJaeger, Prussian Reserve, British Riflemen, Partisans.
If anything, what's slowing down the announced plastic production schedule is... new plastic. Ten kits were released in 2021, 10-12 were released in 2022 (depending on how you count 02 Hundred). 2022 suffered quite a few delays due to relocating the production to the USA as well.
We will have the WGA Commando and German Sentry boxes very soon. WW1 British should be next. I didn't count Ooh-Rah, Harvesters or the Ogres as 2022 as they aren't in all warehouses as yet, but they either count as another three for 2022 or make the start of 2023 a very healthy 5 kits (counting the Commandos and Sentries as 2023 kits).
There's 41 projects on the release schedule. WGA have managed to release roughly one box kit per month in three years of production, which is an extraordinary rate. I do not expect that to drop - it's more likely to pick up a bit now they've sorted out the move - but it's going to take YEARS for all those to reach sales, and the pipeline will always need new product.
