Tetsuya Nomura, the director of the Kingdom Hearts series, made an appearance at E3 2010, the gaming event held in USA earlier. At this event, various parties were able to interview Nomura concerning the English version of Kingdom Hearts Birth by Sleep. GameSpot have reported about this interview, which makes mention of Kingdom Hearts III, which can be read below. The full interview can be read at our forum.
TN: All I can say is that if there were to be a Kingdom Hearts III, then it would be on consoles. I have a desire to create this game, but it's just not the right time. I'm under pressure from KH fans, Disney, and Square Enix, and they all want Kingdom Hearts III. I know this, and I don't hide my desire to make this game. The biggest problem we're facing is our main developer on the franchise is busy with Final Fantasy, and the Birth by Sleep team is busy making Kingdom Hearts for the Nintendo 3DS. But we'll do it when the right time comes.
