Seeing how long K-3 III had been in development stage... My bets are on 2024.
I'm guessing summer 2022.
The thing to remember is that the K-3 III was the first Pentax camera to have a new processing engine for ages. Working out all the details of that, better auto focus algorithms (including face recognition using the OVF), etc took a long time. R and D will be shared between the cameras, meaning the K-1 III will not take quite as long as to finish -- particularly if they mostly keep the current K-1 body shape (no reason why they should change it).
