To speak to the original post: Abriael is pretty much right on the nose. It was stated that while there isn't a firm timeframe to share, the implementation of Ishgard, and related content, will debut after the battle fixes are introduced.

While we understand your enthusiasm to see Ishgard-related content and the upcoming battle fixes, and I know some of you want an exact year/month/day/hour/minute/second, we unfortunately don't have to share at this time.
