Update: Square Enix has released a trailer for the game, which can be seen below.
Original story: Kingdom Hearts I.5 HD ReMIX has been announced by Square Enix, and it’s a bit different from other HD collections.
The game features content from three Kingdom Hearts titles: Kingdom Hearts: Final Mix, Kingdom Hearts Re:Chain of Memories, and Kingdom Hearts: 358/2 Days. While the game contains the entirety of the first two mentioned titles, 358/2 Days will only be represented in the form of cutscenes from the game. All content will be remastered with high-definition visuals, and Kingdom Hearts: Final Mix and Kingdom Hearts Re:Chain of Memories will feature trophy support.
Kingdom Hearts I.5 HD ReMIX will be released in Japan sometime in 2013. A release in other territories has yet to be announced.
