The soon-to-be-released version of FFIV for the Gameboy Advance, featuring enhanced graphics and extra content, will be for sale bundled with the new Gameboy Micro and as a standalone cartridge. The Gameboy Micro bundle will come with the limited-edition custom faceplate designed by series veteran Yoshitaka Amano and will cost 4800 yen, or about $42 US.
FFIV Advance will be on sale in Japan on December 15th. There is not yet any word on a release of this bundle outside of Japan, but such an announcement will likely be made in the next few weeks.
