I'd have to say that it's about time Kyogre and Groudon get their own signature moves, considering the fact that the practice started in Gold and Silver. Latias, Latios, Jirachi, and Deoxys all had signature moves at their introduction, while Rayquaza still doesn't even have an equivalent to Water Spout and Eruption. This leads me to ask, whether it gets a primal form or not, what is the likelihood that Rayquaza will be given a signature move as well, now that new moves for its contemporaries are confirmed?
