Kingdom Hearts III will be placed at the end of the Kingdom Hearts timeline after Dream, Drop, Distance; the Kingdom Hearts title released on the Nintendo 3DS. Believing light and darkness must remain in balance, Master Xehanort seeks to spark war against the 'tyranny of light' to restore equilibrium. In an effort to undermine Xehanort's plot, Sora, Donald and Goofy search for seven guardians of light while King Mickey and Riku search for previous Keyblade wielders.
For those who have not played Birth By Sleep, the Kingdom Hearts game available on the PSP, Master Xehanort has been trying to create a universe with both light and darkness having equal reign, since before Sora first learned of his ability to wield the Keyblade. If not for the efforts of the young Keyblade wielders you control in that game, he would have succeeded. With Xehanort returning to finish what he started, Sora, Riku, King Mickey, Donald, and Goofy will have their work cut out for them.
I cannot express how impatient I am to get my hands on this game. Luckily Kingdom Hearts 1.5 HD ReMIX will be releasing here in America on September 10th, 2013 for the PS3. People who pre-order the game will receive a limited edition art book. This offer is available from the Square Enix store or Gamestop, and is priced at $39.99 USD. I've already got my copy pre-ordered.
Here is the Kingdom Hearts III teaser showcased during E3.
