With Disney's acquisition of Marvel and Lucas Films, Kingdom Hearts creator Tetsuya Nomura stated in an interview at Japan Expo that he is hoping to add Star Wars and Marvel Comics characters in its third installment, Kingdom Hearts III.
Nomura stated, Of course it would be great if we could add those licenses as well, but there are lots of rules and restrictions by Disney so we can't actually put in everything people want. So it's a quite difficult decision but we're gonna prepare some surprises for you so, just wait for the information.
Final Fantasy developer Yoshinori Kitase commented on the topic, We're not going to decide it whether Kitase-san likes Star Wars or not but we've been talking about Star Wars itself since it became Disney's content recently. When I heard the news I was like wow! Obviously it's gonna be great if we could add it.
Kingdom Hearts III was recently announced at E3 2013, and is currently in development for the PlayStation 4.
wow, can't wait for it.
