Yoshida: We’re finally going to release something aside from the end battle content, but the housing and PvP. I believe with this you’ll be able to grasp the full potential of this game. We’ll also expand on the battle content, we are planning to have one brand new dungeon, and also include two hard mode for existing dungeons. This isn’t simply where we are going to swap mobs inside, we’re going to change the dungeons structure, and gimmicks will also change. Difficulty level will also increase. So in total, you will be having three new dungeons.
