So new Pokemon Game Maybe?

Even so, Zekrom and Reshiram have to do with ying and yang, there is no room for a 3rd thing there at all, not to mention the whole dragons backstory only involves the two of them.

So if they do pick Kyurem, it would be stupid, I mean at least Rayquaza looked like Groudon and Kyogre and like how they could be a trio despite Rayquaza not having to do with Groudon's and Kyogre's backstory. Kyurem doesn't even have the same shape tail, let alone look anything more then a fossil stuck in the side of a mountain while the other two actually look like dragons.
