I surely hope so. Even with Delta Episode in ORAS, I don't feel like they've recently invested a lot in post-game content that's not related to breeding/battling. When was the last time (other than Delta Episode) that we had a good post-game content (Looker doesn't count, it was too short IMO)?
The PWT's extra tournaments in BW2, if that can be considered as such. Or for that matter, having a third of Unova locked until post-game.
Game Freak has never really bothered to make decent post-games out of the first paired versions or in remakes.
