Has anyone here considered the possibility that Gen 7 could also be Kalos Sequels? Think about it.
We already know that at least one other Region that is not Kanto, Johto, Hoenn, Sinnoh, Unova, and Kalos exists within this Universe. This is told by the Strange Souvenir guy, as well as AZ mentioning that Kalos was at war with a neighboring Region.
Furthermore, we know that GameFreak made ORAS because they thought the timing was right, and they opted to do it instead of Pokemon Z so they could wrap up the story of XY in a unique way.

Whose to say that the "neighboring Region" Kalos was at war with couldn't be the Gen 7 Region? Like
>>25182958 said, Gen VII will be to Gen VI what Gen II was to Gen I. It may have a lot of references back to Johto, such as Mega Johto Starters, maybe a Sudowoodo Event or something like it, etc. Malva is also a Journalist, which sets up the possibility that Team Flare could return under her control, and she could use her position to try and contact Lysandre (probably operating under the impression that he might still be alive). However, Zygarde would likely still be involved in the plot. Terminus Cave is located right above Couriway Town, which has the Train Station and is known as "The town connecting differences." It's likely that the Train Station connects back to the neighboring Region, and it's likely that Zygarde is connected somehow.
