The release of the fourth major Final Fantasy 14 expansion is delayed by two weeks. Accordingly, Endwalker will be postponed to 07.12.2021 and Early Access will start on 03.12.2021. Producer Naoki Yoshida said the reason for the postponement was to improve server stability.
But to make the wait less difficult, Final Fantasy is combining its postponement with a fresh launch trailer that might give you some hints about what to expect in the big story finale.
