Hmm... I think that S-E missed the big release window for it if they were going to do so. When the FF7 hype was at its highest, with the movie, spin-off games, etc, I'dve said a remake could do 5 million without too much difficulty. It's dying down, though, so if it were to come out next month, I think it would struggle to reach, but would in the end, 4 million. Wait until next year, when the 13 spinoffs are going full circle (Proper, Agito, Versus...), and the hype will move toward 13 and away from 7. Sales of about 3 million, maybe a bit more. Waiting until FF14 will see it bottom out, probably grasping to reach 2.5 million.
