British supermarket chain Tesco has listed an un-announced Call of Duty title, Call of Duty: Ghosts, on their website for PlayStation 3 and Xbox 360 and while the listing was quickly removed screen grabs were taken by AllGamesBeta and NeoGAF.
In addition US retailer Target has also posted a new ad which suggests Call of Duty: Ghosts will launch on November 5th for current generation systems.
A Tesco representative told The Verge that "It was put up accidentally. I think they made a mistake, and that's why they took it back off."
Last month a large image appeared online of Ghost and there have also been rumours that the next game in the Call of Duty saga will indeed be named Ghosts.
While only listings for the PS3 and Xbox 360 versions of the game have been discovered so far it's likely more platforms will be announced in time with a distinct possibility of the title coming to next-gen consoles. Activision's Dan Amrich has suggested the game will be unveiled before E3 in June.
Amrich has also said "We've got a PS4, we've got whatever Xbox is working on."
