I genuinely think that the release we get in October will be mostly vanilla. Any deep and meaningful explanatory stuff will have to be left out or it will ruin the surprise of the final movie. And it is the deep and meaningful stuff that I want to see and hear. I want to know how the story of the sequels evolved from the first film, what compromises had to be made, and what avenues were explored but not taken.
Looking forward to a "Behind the Matrix" kind of feature that delves into the mythology a little bit, and answers some of the questions we have all been obsessing over.
