A user on the GOG forums named Real.Geizterfahr seemed to have caught a glimpse of a Steam listing for Final Fantasy VII. Back in the late 90s, Square (before it was Square Enix) ported FF7 and FF8 to the PC after they were released on the Playstation, but unlike FF8, FF7 has been lacking any updated way to play the game properly.
On the image of the Steam listing(see below), are some new features for this version of the game. They include cloud saves, character booster, and Steam achievements. No word from Square Enix regarding this listing so we'll have to wait and see if this will actually happen.
