UPDATE: Activision claims the countdown timer website is a hoax. "There seems to be a great deal of speculation about the next Call of Duty project," said the publisher in a statement issued this evening. "Let me be clear that we are not revealing yet. Anything indicating otherwise is a hoax."

ORIGINAL STORY: A new website has emerged that suggests Activision will reveal a new Modern Warfare game next week.

According to That Videogame Blog, press have been sent dog tags with a link to the website findmakarov.com. The bloody tags include the message "end the war" along with the details of Sheperd, one of the villains from Modern Warfare 2.

On the website is a countdown timer. There is just under five days left  putting a reveal slap bang in the middle of the Game Developers Conference.

Will we enjoy a Modern Warfare 3 reveal next week? Remember Activision showed the first Modern Warfare 2 teaser at GDC in 2009, complete with release date.

Last month reports suggested Infinity Ward's first game since the headline grabbing sackings of early 2010 would be a prequel to the first Modern Warfare.

Sources claimed the game would be set immediately before the events of Infinity Ward's 2007 shooter, and delve into the backstory of the Ghost character and explain how he was recruited into Task Force 141.

Could Sledgehammer Games be involved in development? Singularity developer Raven is also rumoured to be working on Activision's FPS juggernaut.
