>>22986789Wrong.
There are a total of six "game of origin" values that produce a pentagon on a Pokemon's summary screen. Since the first four correspond to XYORAS, we can assume that the last two will also be the last two games of Gen VI. There are also two unused Ground-type moves whose animations appear to involve Zygarde's hexagonal scales: Thousand Arrows and Thousand Waves.
They did more or less the same thing last generation with Freeze Shock and Ice Burn being included (but unused) in Black and White.
It's pretty fucking blindingly obvious that there will be two new games focusing on Zygarde to close out Gen VI.
