Substance 3D Painter 2023 Steam

Hello, I'm thinking about buying Substances Painter on Steam because I'm not a fan of subscriptions. Now I'm asking myself if I should wait for the 2023 edition.

1. Will the 2023 Edition be available on Steam? 
2. How much will the upgrade from 2022 to 2023 cost with the reduced upgrade price? 
3. When will the 2023 Edition be available? 

4. Will the automatic UV creation tool be improved in 2023 or will it be the same as in 2022? 

thank you in advance.
