Despite aiming not to resort to, Square Enix confirmed that Final Fantasy XVI will receive a Day One patch that fixes:

-Fix a control flag issue that can make progress impossible under very specific circumstances.
-Fix an issue wherein the game could close unexpectedly under very specific circumstances.
-Optimize performance in several places
-Fix some minor text errors

Despite the literal importance, SE claims the game itself is playable without the patch so it won't force it on people, except for the digital version of the game.
