Many Truths, the most important cutscene ever.
Tetsuya Nomura yesterday announced that Many Truths will be revealed at the end of Kingdom Hearts 3D, including the true form of Ansem and Xeanhort, and that many questions will be answered. He also mentioned that the silver haired boy and Axel would be the most important characters. This news means that this will be a pretty much mandatory game for fans, and will most likely be the end of the Story set in motion by Kingdom Hearts 2, allowing us to finally begin part three. In short, the Xehanort Cycle will be completed.
