NieR: Automata, which has sold more than 2.5 million copies worldwide on the PC and the PlayStation 4, will also be released for the Xbox One, according to a source in the French magazine Jeuxvideo, which should be trusted with a pinch of salt. The whole thing is of course just a rumor.
Of course, this is still a rumor, although the writer of the Jeuxvideo article took to Twitter to assure readers that he fully verified his source, and NieR: Automata on Xbox One certainly sounds plausible. So, maybe take this one with only half a pinch of salt.
As it is, Square Enix has never entered into an exclusive console deal with Sony Interactive Entertainment. The decision not to bring “NieR: Automata” to Xbox One was just a matter of budget. Now that the game is a success, an implementation is possible.
