Kingdom Hearts director Tetsuya Nomura provided Famitsu some new information recently regarding the upcoming 3DS iteration. Among a few other tidbits, Nomura is confident that Kingdom Hearts 3D will boast the longest finale cutscene of the entire series, and that during the course of said scene, the true form of series villains Ansem and Xemnas will be revealed. Of course, he didn't elaborate on the fact that this realization will most likely pose more questions.
As long as it doesn't go something like the following, I'm good -- "Now you know my true form! Now you will see me as a truly am! I...am...KINGDOM HEARTS!"
