Could be... But I think we'll either get to have the third element be one from the lower tier (Earth, Water and Air) or from the middle tier(Metal and Wood). Depending on what we didn't get after our attunement test. Though I could see getting an unknown one that is the bridge connecting sun and moon. They answered a player on twitter that Stars is not something this ... but they could do eclipse.
