One of Square Enix's few announcements at the Tokyo Game Show was the reveal of Kingdom Hearts HD 1.5 Remix. This bundle will be released for the PlayStation 3 in Japan next year. It has been confirmed to contain HD versions of Kingdom Hearts Final Mix, Kingdom Hearts Re: Chain of Memories, and HD cutscenes from Kingdom Hearts: 358/2 Days.
There seems to be some confusion over the Kingdom Hearts 358/2 Days content. The cutscenes have been confirmed, but some reports state that the inclusion of that full game is possible. There is also speculation that Kingdom Hearts II could appear in HD in a future remix, but there is currently no word from Square Enix on that front. We also do not yet know if this bundle will be released in North America.
