Pokemon Z?

[Helmo]

I don't think they will add a new pokemon just for Z, unless they do it Gale of Darkness style where Munchlax and Bonsly were there but cameo only. They always show off a new gen pokemon before releasing the next gen, like they did with Togepi, Lucario, etc.

Will they add all the megas from ORAS? Sure
Battle Frontier even? Maybe

I really hope Z fixes Kalos the way Platinum fixed Sinnoh...
