Final Fantasy XVI will feature full facial motion capture for cutscenes, producer Naoki Yoshida confirmed.

Speaking during the Washanaga show, as reported by Siliconera, Yoshida confirmed that the next entry in the series by Square Enix will feature full facial motion capture for cutscenes, which should result in much better facial animations and lip-syncing than Final Fantasy VII Remake, which used AI-generated ones. Additionally, Yoshida confirmed that the team chose voice actors with English accents.
