The October 2013 version update is currently set for "early October." This version update is scheduled to focus mainly on adjustments of existing content and the addition of the "Mog Case." A subsequent update in early November will focus on the addition of new content such as high tier battlefields, new Adoulin areas and content, and upgrades to relic, mythic, empyrean, and artifact equipment.
The next two version updates will march upon Vana'diel in quick succession, with one purported to sortie in early October and the other slated to lay siege in early November.
