In retrospect, the fact that we didn't get a third version for Gen 6 was a huge fucking mistake. Yes, I know, the only reason it didn't happen was because Game Freak didn't plan ahead for the 20th anniversary, so they dropped all related to Gen 6, started work on Gen 7 aka the 20th anniversary celebration, and shoehorned in what little they could like Perfect Zygarde.
A third version of Gen 6 could've vastly improved on what Gen 6 already was. Gen 6 felt so bare and incomplete, it NEEDED a third version. Badly.
