Hello. While the translator team does a tremendously good job at keeping Yoshida's letters personalized and informative, I have come across one issue that you may have overlooked- how the reader perceives the letter as opposed to those working on the game. This may be partly Yoshida's 'fault' as well, either way, let me explain.

Recently in the letter VIII Yoshida had to correct a few misconceptions regarding the development procedures, particularly how the workflow has been set-up and what the current and upcoming patches are set to accomplish. While looking closely at the past letters the big picture started becoming clearer for me, but only after having been explained in the letter VIII how the development team operates. These two parts from letters I and III in particular peaked my interest:

I:
Though the next version update will introduce a relatively small number of changes, preparations are already underway to bring further improvements in the near future via a number of smaller-scale patches, including the release of quests and system-side adjustments. At present, we intend for something new to be released about twice a month. Overhauls to the battle system and user interface will also be ongoing, which will make it easier for the players to enjoy the new quests and content being released. The small-scale, system-oriented updates that will be carried out can best be thought of as the necessary groundwork for the battle system revisions.
Here the wording 'overhauls to the battle system and user interface will be ongoing' makes it sound like the overhauls are a part of the smaller-scale system-side adjustments that release twice a month. Further, initially it was easy to mix the quite small second patch of the month (1.15b, 1.16a, etc.) as the "small-scale, system oriented update that can best be thought as the necessary groundwork for the battle system revisions (which will be ongoing and part of the larger "revision" patches (1.15a, 1.16, 1.17...)". However, letter VIII states that in fact, every patch up until now has been a small-scale, system-oriented update and the battle system revisions have not yet been implemented after all (although every patch has seen some battle-related adjustments, making this kind of wrong thought-process more believable).

III:
But after-the-fact adjustments and reworkings being what they are, it simply isn't possibly to fit everything that needs to be done in a single monthly patch. And so we're planning to release every big change over the course of two smaller-size updates. You'll be able to start seeing the changes to the battle system come spring, so please be patient just a bit longer!
Here I think it was easy to confuse the "two smaller-size update" as the "small-scale, system-oriented update that will be released around twice a month", while from the letter VIII as well as some recent interviews an assumption can be made that these two "smaller-size updates" are something separate from the current patches after all.

Now, I think that the problem here is the lack of proper terminology to explain the philosophy behind the development procedure and the lack of thinking like you'd "be in our shoes", in other words while to you guys this is all pretty self-explanatory, we as the community do not know the inner operations of the development team and thus need a clearer explanation and terms that we won't confuse with each other.

So, in the future to avoid these kind of misconceptions from arising I hope you can figure out how to explain these things to us in a way that leaves as little room for interpretation as possible.
