During the opening of Square Enix's Tokyo Game Show booth the company has announced Kingdom Hearts 1.5 HD ReMIX for PlayStation 3 to celebrate the 10th anniversary of the Kingdom Hearts series.
This HD collection will consist of three games: Kingdom Hearts: Final Mix (released in 2002 on PlayStation 2), Kingdom Hearts: Re:Chain of Memories (released in 2007 on PlayStation 2) and Kingdom Hearts: 358/2 Days (released on Nintendo DS in 2009), which will NOT be the full game, only the cutscenes.
