Square Enix has announced at the Tokyo Game Show a new collection bundleware for the PlayStation 3: Kingdom Hearts 1.5 HD Remix, which will include remastered versions of Kingdom Hearts: Final Mix, Kingdom Hearts: Chain of Memories, and Kingdom Hearts: 358/2 Days.
Final Mix is the “definitive” version of the original Kingdom Hearts, while Chain of Memories and 358/2 were Nintendo handheld origins from the Nintendo GBA and the Nintendo DS respectively.
Nothing else is known about the game, except that the Japanese release will be sometime in 2013.
