The Anime hasn't had any hints for what's next. Nothing has been shown in the Anime to say we're getting remakes at all. All we know from the Anime that the Unova League is over and they starting the Plasma Arc which may or may not be as long as the Unova League. Hell Team Rocket Arc was like what? 3 episodes? At the end of that was the first hint to a new game but we all doubt that Kanto is coming back.
No Hoenn references have been made in the Anime, so there is no anime support for remakes yet.
