During the latest Letter from the Producer Live broadcast, Final Fantasy XIV: A Realm  Reborn Producer and Director Naoki Yoshida gave the rundown of what we can expect from the upcoming expansion Heavensward, that will be released on June 23rd for PS4, PS3 and PC.

• The expansion includes over 50 hours of gameplay for the main scenario quest, with more coming with further patches numbered from 3.1 onwards.
• New quests will be introduced, including new job quests for both existing and new jobs, including crafters and gatherers, up to level 60.
• New areas will be betweet 50 and 100% bigger than the existing ones, and there will be nine of them.
• Flying mounts will be able to land and take off without restrictions. Flight will be possible in all expansion areas, but not in the old ones.
• Leveling of the new jobs will start from level 30 instead of going all the way from level 1.
• Multiple new actions will be added to every job. Level 3 limit breaks will be specific to each job, with the existing ones distributed among three of the existing jobs.

• New recipes and Materia V will be added for crafters.
• Crafters will have a specialization system for three classes of their chosing. They'll still be able to level to 60 in all classes. "Scripts" will be used to change specialization. Each specialization will have access to specialist actions.
