Why would FFVIII be more likely....Kitase gave an excuse stating PS3 made 'towns and full rendered backgrounds made production too expensive'. That pretty much knocks out any FF game past FFVI for a remake if he's going to make it. Unless they try to produce it in a different style than the way they've been making games currently.
Frankly, I think they could make a new Final Fantasy a lot cheaper and more cost effective than the recent FFVII-FFXIII has been, but that's just my opinion. Other JRPGs can produce games at 1/10 the cost of a FF game and still look quite fine. Look at Dragon Quest VIII, Star Ocean IV, Lost Odyssey, etc. A game doesn't have to have a 500 million dollar budget to make 500 million dollars.
