These are all rumors. The last time Square was asked about this, they said they had no plans to remake these games at this time. If they ever do, it will be a long way down the line.

Don't believe what people on the internet say. If it isnt in an official game magazine of an official site (and that means SquareEnix's official site, not a fan site like this one), its a load of bull. These rumors fly constantly, and they're all bogus.
