British retailer Tesco might have just accidentally outed the next Call of Duty game subtitled.

That's according to a product listing on Tesco Direct (the object has now been pulled down). This would tally with recent reports that the next instalment in the hugely-successful franchise would be subtitled 'Ghosts', which came from YouTube user Drift0r.

The listing also features credible box art bearing the Infinity Ward logo. The Infinity Ward studio previously worked on the tremendously popular 'Modern Warfare' entries in the long-running franchise. This would make sense since last year's Black Ops II was made by Treyarch. Has the Modern Warfare title been dropped following the high-profile departure and out-of-court settlement with Jason West and Vince Zampella?

The page also has a release date of December 30th – if correct, this would be unusual for the shooter which typically launches in early November. We expect it's just a placeholder.

A potential teaser for Call of Duty: Ghosts has appeared on the franchise’s official site. An image is slowly being built on a new teaser page, populated based on Tweets using the #CallofDuty hashtag.

While the image isn’t complete yet, it appears to be taking the shape of the mask of Simon “Ghost” Riley, the British soldier last seen in Call of Duty: Modern Warfare 2. This would add credence to recent rumors that the next Call of Duty is called “Ghosts,” including retail listings that show off a potential box art.

The next entry in the Call of Duty franchise is expected to be revealed on May 1st.

As expected, Activision has officially announced Call of Duty: Ghosts. Set for release on November 5th, Ghosts comes from original Call of Duty studio Infinity Ward and will hit Xbox 360, PlayStation 3 and PC in addition to being "available for next generation platforms."

According to Activision, Ghosts "delivers a riveting all-new gameplay experience built on an entirely new story, setting and cast of characters, all powered by a new, next generation Call of Duty engine that redefines the series for the next generation."

Confirming a retailer leak from last week, Activision showed off the game’s official box art and logo as well as a live action trailer hinting at what Ghosts has to offer. Activision also launched the game's official Facebook page.

“Everyone was expecting us to make Modern Warfare 4, which would have been the safe thing to do," said Infinity Ward executive producer Mark Rubin, "but we're not resting on our laurels. We saw the console transition as the perfect opportunity to start a new chapter for Call of Duty. So we're building a new sub-brand, a new engine, and a lot of new ideas and experiences for our players. We can't wait to share them with our community."

“Infinity Ward set the gold standard for first-person action for a generation, and they’re going to do it again with Call of Duty: Ghosts,” said Activision Publishing CEO Eric Hirshberg. “Ghosts delivers an all-new story, all-new characters, an all-new Call of Duty world, all powered by a next generation Call of Duty engine, which is a leap forward for the franchise. Infinity Ward is going all-in to create the next generation of Call of Duty worthy of the world’s greatest fans."

This marks Activision’s first official acknowledgement of Ghosts, following several leaks and early information via promotional material provided to IGN.

Little else is known about Ghosts, but Activision hints that much more will be coming during Microsoft’s announcement of the next Xbox on May 21st. Expect to find out more about Ghosts then, plus get "an exclusive first look at the game."
