There already is another game. Chain of Memories. However, I agree, this series is going to go on. Is it really that surprising? KH may have been a gamble, but it payed off big time. Now there are entire worlds open that Square and Disney can fit into the storyline, and thanks to Deep Dive and Chain of Memories, there are a truly massive number of plot options open to explore as well. The Organization, DiZ, and the other side of the heart are the most obvious. We know that they are going to show up in KHII. But I really suspect that while we will learn a lot about the things that are currently driving us crazy, we're going to be left with even more questions that will be addressed in KHIII. And I wouldn't have it any other way.
