I don't think it would be economically viable for them. Why put millions into the remake something like FFVIII or FFVII, which is probably still selling copies of the original (I only bought FFVIII about 6 months ago), when they can put millions into a brand new FF, which will sell anyway.

Yes it'd be nice, but I don't think its happening. They probably wouldn't make much money from it, so it would be just a favour to FF fanatics........so don't count that.
