From what I've read, this game still has you repeat content, it's just done a bit differently than it was in the first game (and it's also once instead of four times, but longer). I've also heard that it contains some of the same content/areas as the original game, so yeah, this game is very much "more of the same." If you didn't like Bravely Default, nothing here will change your mind.
I'll probably still buy into it since I liked the class system well enough.
