Though Square Enix announced several weeks ago that the American release date of FFIV for the GBA was December 12th, the Japanese release was given the less definite target of "December 2005." The official day has been confirmed now, though--FFIV will once again be hitting store shelves in its enhanced, portable version on December 15th. This is interesting to note because it's one of the few releases of a Japanese game to come later in Japan than in the United States. There's no word yet as to whether or not this version of FFIV will see the light of day in other parts of the world.
