On May 24th
Final Fantasy XIV: A Realm Reborn is still operating on its major update schedule before a full expansion drops, and the most anticipated update currently is patch 2.3. It's expected to bring about new dungeons (Hullbreaker Isle is mentioned, as are hard mode versions of Tam-Tara Deepcroft and Stone Vigil.), daily hunts, Item Desynthesis, a new boss fight with Ramuh, and additional Zodiac weapon quests (coming directly beforehand with patch 2.28).
Director Yoshi-P (Naoki Yoshida) will deliver a letter from the producer address on May 24th at 4:00 AM PST to answer some questions on the upcoming content. I'm mostly excited about Ramuh, and potential Extreme Mode remixed boss fights.
