I am a big fan on Final Fantasy VII as it was one of the games I loved from that era, but lets be honest here, there is no way they will be making a remake of the game and who would actually WANT one?
Seriously, look at SE's track record so far with the current Final Fantasy games, do you really want it to go in that direction? A closed claustrophobic game where you can't even control all of your party members and having the game more focused on graphics than game play?
I would believe it would lose everything that made Final Fantasy VII great.
Also, if you wanted it for an actual console like PS3, good luck, according to Yoshinori Kitase the producer of Final Fantasy XIII it could take up to 12 years to develop. Probably a gross over estimation but even if took half that long, 6 years, that is still probably longer than the rest of the develop cycle for the system in question.
