RUMOR: Final Fantasy XVI devs may be hinting at a Switch 2 port
Will fantasy become reality?
Final Fantasy XVI producer Naoki Yoshida and creative director Kazutoyo Maehiro just appeared on a "Letter from the Producer" live-stream to discuss the game's recent arrival on Xbox Series X/S. During part of the discussion, Yoshida says that "just Nintendo's left" in reference to modern platforms where Final Fantasy XVI isn't yet available, to which Maehiro responds by saying he "will do his best."
This isn't a flat-out confirmation of Final Fantasy XVI coming to Switch 2, but Square Enix and the game's team obviously know that fans are watching these videos and will start speculating the moment they make any reference. This little back-and-forth is at least enough to give very slight hope that we could see Final Fantasy XVI arrive on Switch 2 at some point.
