That's when they're waiting to release FFXV.

Seriously, I'd like to see a total remake of the first one, somewhat similar to what they did for III. Have all 6 characters @ your disposal w/ distinct personalities. Give it a more fleshed-out storyline. The battle system could be close to what X has, where you have 3 in battle & can switch out any of them mid battle, as well as making it like XII where you don't get a game over until ALL 6 characters are dead.

Also give the characters job specific techniques. Let the Thief steal. The Ninja could have Mug. The Red Wizard could have double cast. Stuff like that.
