Recently, Ni no Kuni II: Revenant Kingdom was listed as an Xbox One game on Spanish Amazon. Now the Spanish edition of IGN has chimed in on the matter and saying they've heard from credible sources that the game will in fact be released for Xbox One.
They do say that it will be digital only except in UK, and we've reached out to Bandai Namco for a comment. This is still no official confirmation, but if you want to play a promising Japanese RPG on your brand new Xbox One X next year - chances are looking decent.
