In the most recent issue of Game Informer, Tetsuya Nomura has revealed during an interview that he will be bringing a new game with him when he attends this year's E3 event.
Nomura said that the game "came into existence because we wanted to do something for the North American fans, so we’ll be announcing it at E3." By using the term "announcing", it is certainly not a game we have been shown before.
Aside from working on Final Fantasy XIII Versus (a game which he said was unsure would be able to make it to the yearly event), Nomura has mentioned that he is working on two other Kingdom Hearts titles, with one of them speculated to be Kingdom Hearts 3.
Members of RPGSite will be attending E3 2010, so stay tuned to our site as we learn a lot more about this latest revelation!
