After re-watching the Princess Twilight Sparkle arch for the third time I noticed something peculiar about the scene where Princesses Luna and Celestia confronted Discord. When they took out the Elements of Harmony, each was carrying three in their sattle bags. Celestia had been carrying the elements of Magic, Kindness, and Generosity; Luna carried the elements of Honesty, Loyalty, and Laughter. Could this mean that those are the elements that each represented before the main six came along?
