>Armored evolutions don't actually exist in this game, but are mentioned and will probably be included in the 3rd version of the game.
>Post-game has massive loads of content, including exploring parts (not all) of Kalos and the return of the Battle Frontier
>Regional variants are returning, and they are mostly for Johto and Sinnoh Pokemon
>I've been told that the legendaries are Steel/Dark and Steel/Psychic, but I'm not 100% sure if that was true
Lots of new Pokemon, estimated around 120, and include evolutions for old Pokemon (not Dunsparce or Shuckle, sadly)
>Final starter evolutions will be Fire/Electric, Grass/Dark, and Water/Dragon
Old characters will return throughout the game, most being from Sinnoh and Kalos.
>Only new Mega Evos are for Johto and Sinnoh Starters
>Lastly, your rival starts off friendly, but get more competitive and mean throughout the course of the game, and I heard a rumor he joins the evil team near the climax of the game.
>Sinnoh remakes come out next year.
