I hope her inclusion paves way for a Xenoblade Chronicles X remake, or should we be lucky, Chronicles X-2.
Given the ending of Xenoblade 2 in the context of 1, and the mysteries inherent to the planet in X, and the overall cosmic cyclical tendencies of the Xeno- games, I have a sneaking suspicion that if we ever get a sequel rather than parallel events game to any of the three Xenoblade games it'll turn out to be a sequel to all three.
