A promotional poster for Lightning Returns: Final Fantasy 13 shows PC listed alongside PlayStation 3 and Xbox 360, something of an aberration for the console-focused franchise.
Destructoid has a photo of the poster in a bus shelter in Los Angeles.
No other promotional materials - including the RPG's website - show the PC logo.
We've fired off a deeply curious email to Square Enix, but as its PR reps are probably all in or on their way to Los Angeles - perhaps for a big Final Fantasy reveal at Sony's press conference or the publisher's own broadcasts? - we're unlikely to get a response in a hurry.
Some Final Fantasy games have released on PC, but usually well after console release.
