Akihiro Hino, CEO of Level-5 and director of Ni no Kuni II:Revenant Kingdom, has put together a short video announcing a delay of the game and a clarification of an error made in a previous interview. In the video, viewable below — make sure to turn on subtitles — Hino states that the game will arrive for the PlayStation 4 and PC in January 2018. He also made clear that the game will not feature any sort of multiplayer, only certain online features.
Ni no Kuni II follows Evan, the deposed boy king of the fantasy world of Ding Dong Dell. Throughout the game, Evan is on a mission to secure his throne and kingdom. For more information on a recent build of the game, more can be learned about the game through Harry Papadimitriou's impression here.
