Kingdom Hearts series director Tetsuya Nomura has strongly hinted that a HD remake of Kingdom Hearts 2 is on its way.
Square Enix will next year release Kingdom Hearts HD 1.5 Remix, a three-game compilation featuring HD versions of Kingdom Hearts, Kingdom Hearts: Chain of Memories, and Kingdom Hearts 358/2 on one disc. But oddly, no Kingdom Hearts 2.
But in a chat with Nomura recently, Japan's Famitsu asked if there will be a KH2 remake later, to which the director replied, "It'd be unusual if there wasn't," (thanks Gematsu). Make of that what you will.
Square released the first trailer last week showcasing the HD compilation. Kingdom Hearts HD 1.5 Remix releases in Japan next year.
