Looking at the current work, it seems that the team is only working on the mod. I haven't seen any new progress on the major graphics update on the forum in nearly 2 years. If it's still in development, I'm guessing the Graphics update won't arrive until at least 2030. It looks like we don't have time to see the other big updates (dynamic weather, rain). (we're all getting old)
I don't react to the slow development of the game. After all, it was developed by 3 people and continues to be developed. I want people to know how the real progress in graphics and physics is going.
Don't misunderstand my answer, we all enjoy playing this game. However, new major developments excite us and give us hope.
