Nope, I don't see it happening. As great as it is (one of my personal favourites) it isn't as well recieved as many FF titles. Although I have spotted a trend in games that recieve a prequel/sequel.

FFIV: First SNES era game, got a sequel
FFVII: First PS era game, got many sequels and prequels
FFX: First PS2 era game, got a sequel
FFXII:First PS3 era game, got a sequel

The only other FF to buck the trend was XII with Revenant Wings, but that was a DS only game so it wasn't really made to sell millions.

Edit: Recently bought IX on PSN. Playing it on my PS3. 10 years on and it still beats most of the games of today.
