Ok, so finally after a week of silence, the Lodestone posted something. Not really news, but I thought I'd share it anyway for those of us (including me) who don't peruse the FFXIV forums on a regular basis, or at all, for information and may have missed the re-cap of the live letter.
Here's the link to the Lodestone post with the english subtitled Q&A session summary of the Letter from the Producer LIVE part IV: http://forum.square-enix.com/ffxiv/threads/58180
There is also a written transcription of the Q&A session below the video link, if you're not keen on watching a near two-hour video.
