PC Gamer reports that NieR: Automata will be released in 2017 for the PC, but not on the same day as the console versions:

Nier: Automata has a new trailer, but no firm release date for PC as yet

Update: previous parallel release with PS4 was wrong, rep says.

The Square Enix rep who confirmed the PC release date would fall on the same day as the PS4 version in the West was unfortunately misinformed: officially, there's not yet a release date for Nier: Automata on PC, though it's definitely coming some time next year.
