Square Enix's latest Final Fantasy game, Final Fantasy 16, recently turned six months old. At this point next year, FF16 will be more than eighteen months old with two of its post-launch expansions already out and, quite possibly, its PC port as well.
Square hasn't confirmed when FF16 is headed to PC yet. The last we heard of the game was in December when, among other things, the game's director, Naoki Yoshida, teased the heavy hardware requirements for it to run well on desktops, which is expected, the PlayStation 5, which is equivalent to a decent gaming PC, struggled to run it. But, while Square has its hands full shining the spotlight on Final Fantasy 7 Rebirth ahead of its release on February 29, content creator and industry insider, @Genki_JPN, highlighted a statement by Square last November.
As part of its most recent investor Q&A, Square Enix confirmed that, aside from being pleased with the sales of FF16 at the time, it plans to maximize the game's sales over the next year and a half by releasing "downloadable content & the PC version when the timing is optimal."
Square released the first DLC for FF16, Echoes of the Fallen, on December 7, while The Rising Tide is set for Spring 2024, which is anywhere between March 19 and June 21. The best bet is for its release is in June, in time for FF16's one-year anniversary and the usual annual June gaming festivities. Then, the PC port release date should be announced a few months later, possibly in August or September, ahead of its presumed December release to take advantage of the holiday season.
