I just watched this, and this does make some sense. Ignore the first half about the Zygarde and Greninja parts, but the parts I focused on was the "Flowers" cryptic word, and then looking at Belgium and the Netherlands (aka the land of flowers). Having Belgium and the Netherlands being added to Kalos in the next game makes so much sense. Especially with the map from the anime showing the locations of the gyms (I think that's what it showed, there were red dots) and they were east of frost cavern across the bridge, and one in the rocky area behind it.
