There is a long interview on famitsu, but not really much detail on the game (it seems funny interview though)
(...)
-In past DOA games you (the player) are the one who is controlling the character, but with the new Owner mode, the character is focusing her attention to you (the player). DOAX1 was out 13 years ago, and the idol culture have changed a lot over the years. Back then, people were satisfied with just looking at those idols. But now, the fan's relationship with the idol is much closer, and they want the idol's attention. So instead of just looking at girls, we wanted the players to interact with the girls this time.
-When we thought of the owner mode, we also decided to implement PSVR feature. We haven't actually made the PSVR feature yet, but we want to have the feature ready when PSVR hits the shelves.
