Well, i think first they need to make a battle system where being in a group isn't pointless spamming of abilities.
And to do that, they are going to need to have defined jobs/roles and not a bastardized armory system, and have it in effect at level 1 (if they want new players to pick up this game).
And with the speed that "major" changes are made... um... 3 years?
Eventually they'll change the name to final fantasy forever! It will re-release in 12 years.
