Square Enix has released a new batch for Kingdom Hearts HD 2.5 ReMIX. Due out later this year, Kingdom Hearts HD 2.5 ReMIX includes Kingdom Hearts 2 Final Mix, Birth by Sleep Final Mix, and HD cinematics from Re:coded. It's actually the first time the Final Mix versions of Kingdom Hearts 2 and Birth by Sleep will be available in North America, as the two games were previously exclusive to Japan.
Square Enix hasn't yet announced an official release date for Kingdom Hearts HD 2.5 ReMIX, but did reiterate that it's coming some time this year. In the meantime, enjoy the screenshots.
For those looking to get into the series before the release of Kingdom Hearts 3, I suggest first playing Kingdom Hearts HD 1.5 ReMIX which is another bundle that includes Kingdom Hearts Final Mix, Re: Chain of Memories, and HD cinematics for 358/2 Days.
