have a theory on how Revolutions will play out:
1) Reloaded set up a revelation bigger than the first matrix, the alternate matrix, ZION.
2) Remember in the first movie how Morpheus explained that the "man born inside the matrix" freed the first humans? I think that Neo is going to take that role again. He will be the only one who will know that ZION is still the matrix.It will a reversal role, instead of Morpheus being the person who reveals the matrix, Neo will take on the role of his predescessors, in ` "freeing the first humans from the matrix."
3) Since Neo is the first one to take the other door, Zion will not be immediately destroyed,
therefore Neo, unlike the other "ones", will have time to explain the other matrix to the
remaining humans, and at last free them of the matrix, to the real, real world.
4) The fight in Zion takes place because, remember, if you are killed in the matrix, you die in the real world, that is why a strike is ordered, so 250,000 dont really wake up!!!
5) Neo must defeat Smith, because he can take over the entire first matrix and kill everyone
connected to it, there would be no one to wake up.
6) I think it makes perfect sense, take the success of the first movie, and copy in the second. In the end, they will finally be free in a beatiful real world!!!!!!
