Like any other person, He has things to do, and things to go, maybe more importantly than testing-releasing the patch, it's not a simple task to achieve, it requires a lot of time and effort to be completed even at a bad state.
Remember that this is a voluntary work, that He did(Or maybe does) in his free time, so, we have to wait patiently until a new update or a final release of the patch.
Apart of this, we can assume 3 possible scenarios:
1. Nearly null free time to spend to complete the translation of the game.
2. He's ill or something similar (I hope He is doing well).
3. He just lost all motivation to continue this project or make the patch for the game, even if it's already translated fully with some errors.
I think those are the most possible scenarios to think of.
Again, we don't know about the other people's life, some people live in a wooden house, some people nearly has the chance to access the internet, some people don't have a family to rely on, some people live to the limits...in such odd conditions, that's why we are wrong judging a person to not release something if we don't know how the other person is doing, or which situation is facing right now.
So, what we have to do now, is wait, for something to be announced by the Librarian Shepherd, that's all.
