I've just been made aware that Yoshi-P visited the Chocobo server (JP datacenter) and answered some questions today. (Source is here:
http://blog.livedoor.jp/umadori0726/.../61125701.html , I do not speak Japanese but got a translation from a Discord server; just to check, I did a Google translation and it supports the actual human translation so I'm safely assuming the human translation is the more accurate version)
Specifically relevant to this thread:
Not gonna pretend it's much (at its core, it's just "Soon(TM)"), but it's the most significant update I've heard in a fairly long while, even checking other translated interviews and such.
Given the wording of "wait patiently", I'm not expecting the update in Dawntrail's release... but maybe we'll see something in the Dawntrail patches rather than having to wait forever?
