Here's some of the more titillating excerpts: The game features a reinvented character progression system which does not include experience points or leveling up. The job system from XI will make an appearance, but in a heavily altered form -- an interview with the game's director, Nobuaki Komoto, revealed that the game will place a focus on the weapons players use, explaining that your armaments will determine "the way you play" and "the way you grow." Sounds reminiscent of Final Fantasy IX. (That's a very good thing.)
In addition, FFXIV producer Hiromichi Tanaka explained that the game takes place in a new region with a more "modern" feel to it -- the mysterious Eorzea which was mentioned in the trailer. The new world features familiar races (albeit with new names), and plays host to a "deep story," which is told through cut-scenes and quests.
