For a recent and extremely long period live broadcast to support Final Fantasy 14, producer Naoki Yoshida gave away some information about the other game he is currently producing: Final Fantasy 16. Above all, what he said he did not expect to see at the Tokyo Game Show this September / October.
However, development seems to be reaching a decent pace. According to the translation courtesy of Twitch streamer Father Kimochi, the scenarios have been completely written and the recording for the English voice is about to be done. What will probably take you away from the Tokyo Game Show this year is perfectionism and the desire not to give away long before Final Fantasy 16 is ready for release.
According to Kimochi, Yoshida mentioned the battle system and "things that haven't even been touched yet" would be in the next announcement, but that announcement won't be ready until shortly before launch.
We expect Final Fantasy 16 to hit the PC shortly after a brief window of PlayStation 5 exclusivity, but Sony is still having issues with this.
