According to IGN, an Activision spokesperson issued this statement to them explicitly stating, 

"There seems to be a great deal of speculation about the next Call of Duty project. Let me be clear that we are not revealing yet. Anything indicating otherwise is a hoax." 

This just kicked off. A countdown website known as “findmakarov.com” has appeared online. Modern Warfare 3 season? Looks like it.

Countdown’s at under five days right now. In addition, TVGB received promotional dog tags from Activision which led to the site. It also contains information on MW2 character Shepard.

The tags proclaim “End the War”.

Sounds like a GDC reveal to us. Modern Warfare 2 was also first shown at the event two years ago.

A lot’s changed since that showing, though. Infinity Ward studio heads Vince Zampella and Jason West were fired by Activision for “insubordination”, and have gone on to find Respawn Entertainment.

Both men as well as others are suing Activision for unseen royalties from MW2. Activision is also counter-suing Zampella, West and EA, who will distribute and publish the studio’s first game.

It’s rumoured that Infinity Ward, Sledgehammer and Raven Software are currently working on the game together.

On the Rumour Machine page in its latest issue (055), OPM points to ""insider whispers" which suggest: "Infinity Ward's next Modern Warfare title will be a prequel, with Ghost in the lead role."

Other wicked whispers featured on the page include the suggestion that "Dead Space 3 is already in production" and that PS2 games will soon be available to download on PSP.
