At X019, when they announced all those Final Fantasy games for Game Pass, Phil had this to say
The big two games missing from this list are Final Fantasy ’s two MMOs, Final Fantasy XI and XIV . However, speaking to members of the press at X019 earlier today, Microsoft’s gaming chief, Phil Spencer, said that the company plans to bring Final Fantasy 14 to the service at a later date. “I wanted you to know, rest assured that we will be bringing that game to Xbox,” said Spencer. “We have a great relationship with Yoshida-san and we’re working through what it means to bring [to Xbox] a cross-platform MMO that they’ve run for years.”
That seems pretty cut and dry. “We will be bringing that game to Xbox.”
Now here is Phil in 2022 saying they’re still committed to it:
Asked about the status of the Xbox version by Game Watch this week, Spencer replied: “We certainly announced that (laughs). Naturally, we haven’t given up yet. This is a commitment from both Microsoft and Square Enix to gamers and we will continue to coordinate our efforts.”
