Call of Duty: Modern Warfare 3 will be released on November 8th, 2011 on Xbox 360, PlayStation 3 and PC. It's being made by Infinity Ward, Sledgehammer Games and Raven Software as a joint effort to make the best Call of Duty game ever.
The game will see the return of Task Force 141 Captain John "Soap" MacTavish and former SAS Captain John Price, with Vladimir Makarov as the game's main antagonist. MW3's multiplayer will be done by Raven Software, which means that modern warfare 3 will have the best multiplayer experience to date. The modern warfare 3 perks system will have familiar perks returning from MW2, but most of the MW3 perks will be new and/or enhanced. The multiplayer experience will also have a lot of new weapons and attachments, and the modern warfare 3 weapons will be even more customizable than before.
Just like Modern Warfare 2, MW3 will be supported after release and will have increased security against cheaters on both Xbox 360 (XBOX Live) and PlayStation 3 (PSN).
