There is already an almost unprecedented number of content expansions announced for Final Fantasy V with four already detailed and two still to be revealed (and that's on top of add-ons and pro-order bonuses). But why stop there? Square Enix seems to be going all in and Siliconera (via Jeux Video) reports that they are now considering even more DLC that will let us play as one of the female characters, like Luna.
The company says it all depends on demand, but building adventures like this takes a lot of time. If Square Enix starts after the game islaunched, it could be at least a year away, maybe even approaching two. Chances are that they have already started, and hopefully we'll get to see stories with heroines Aranea or Gentiana as well.
