Nier's sequel was announced at E3 2015, and they announced it will be co-developed by both Square Enix and PlatinumGames.

Designer Yasuhisa Taura revealed that PlatinumGames will be handling the majority of Nier's sequel, however, they are getting help from Square Enix, the game's original music composer, and character designer Akihiko Yoshida.

"Yes, the development is mostly taking place here at Platinum [in Osaka], and in our Tokyo office, but we are of course getting help from Square Enix, and the composer for the original game is back to make new music. Also, the character design is being done by Akihiko Yoshida who works on CyDesignation, so we are borrowing people from other companies. But the majority of development is being done here."

Nier's sequel is one of the PS4 exclusives that I can't wait to hear more about.
