I am on one of the most popular servers of MGQ and there are translators like ArzorX and Kaerdron.Come back around mid 2027 or early 2028, the translation should be close to be done around that time*.
*This is my personal guess, I don't have anything to do with the translators. Also, this is considering that the game releases this year and disconsidering any post-game content, like the crossover that we had.
And from what I was able to discuss on the server and thanks to other people on servers dedicated to SHRIFT or others, a large quantity of documents could be found (but no spoilers. it's the rule). And it seemed to me that one of the translators had said that thanks to new technologies or software, it can be faster to translate but already, ArzorX and the others are already doing a great job with regular updates (because it is not only necessary to translate but to make sure that there are no bugs or crashes).
The problem on the other hand is that there are many files and they do not know if they have done a lot or a little and especially that there may be other elements added by TTR.
So it will depend but it remains 50/50.
