The set numbers though. The Arcade Pods are 71714 - 71716, the unknown ones are 71717 and 71718, and the normal sets are 71706 - 71713. Usually wouldn't be that far away from the other non-gimmick (spinnner/flyer/whatever) sets. It's also possible there are no Earth and Lightning chapter, or perhaps one chapter will also use elements of the Legacy sets.
