Update: Square Enix has told us that the release date listed by Amazon is factually incorrect, while reiterating that the game is set for release in 2013.
The online retailer updated its pre-order page with the Friday release date earlier this week, Examiner reports.
It may well just be a placeholder though, as Famitsu reported last month that the PS3 and Xbox 360 game is just 30 per cent complete.
Revealed at a Final Fantasy 25th anniversary event in September and set for release some time next year, the game is being billed as the last entry in the "Lightning saga". It'll feature the FFXIII heroine in a tense finale as a doomsday clock counts down 13 days until the end of the world.
