Actually the third movie leaves no questions left. All the questions that were left hanging from the first two are answered. The story is complete resolved on revolutions. Trust me
I just read the Rolling Stone Review and all I have to say is stick to hiring hot girls for the covers. They completely missed the whole point of the ending. Neo was never meant to destroy anything, he was the messiah, "Jesus", Jesus\' death didn\'t bring the destruction of something, it brought peace between humans and pardoned them for their sins. Neo did the same, he didn\'t destroy the enemy he made peace with them. I don\'t think they hinted for any other sequel, the architect, like mentioned in the movie, is all about balancing equations. Therefore his take on the peace not lasting is his way of seeing the equation balanced. But like the oracle also mentions in the movie, he doesn\'t capture the idea of choice and hope. The sun rising I think represents the new beginning or era of peace between the humans and the machines. With a sunrise you get the feelings of something new, like the new life of the people of zion and the matrix. The ending was the best way to let this movie go out. I bet all those critics failed literature class when they had to analyze books...which Im doing now so Adios!!
