According to reports, the game is being jointly developed by Infinity Ward, developer of ‘Call of Duty’, with Raven Software taking charge of the multiplayer development and Sledgehammer Games – an Activision division - involved with the single player scenario.

The teaser did not include any gameplay or cinematic clippings but showed New York as a possible arena for the game.

Reports also suggested that Activision had no option but to release trailers after widespread leaks in many gaming sites about ‘Modern Warfare 3.’
