I don't believe for one second that they would ever touch this game again.
FFXV is a far more beloved FF than FFII, but that game got a full 2D remake on PSP. It's a lot more popular than FFIII, too, and that game got a full 3D remake on DS. It's more mainstream than FFXII, even after FFXII's HD remaster, but the most recent HD remaster added features that didn't exist in the original HD remaster (which added features that didn't exist in the original IZJS, which added features that didn't exist in the original game).
...with that said, I doubt that updated rereleases will be significantly updated. They'd probably, like, hide the overpowered DLC weapons in endgame areas rather than give them to players from the beginning, up the resolution, use the ultra PC settings, and add an audio track with Dawn of the Future material (the way they did for that travesty of a FFX sequel novel =P ). But that's still very different from refusing to touch the game again.
