found this on IGN it looks good and like MW2 so could be real

Kotaku has posted a large amount of information on this year's Call of
Duty game, claiming the details have all been verified by anonymous
sources. There's no official word from Activision yet, but according to the Kotaku story
the next Call of Duty game will be called Modern Warfare 3 and jointly
developed by Infinity Ward, Sledgehammer Games and Raven Software. The
release date will be November 8, 2011.


The single-player story will start directly after the events of Modern
Warfare 2. The villain Vladimir Makarov and heroes "Soap" MacTavish and
John Price return in 15 stages set across the world, including New York
City, Dubai and Paris.


The Spec Ops co-operative mode from Modern Warfare 2 will return, as
well as survival maps that sound similar to Gears of War's horde mode or
Call of Duty: World at War's zombie mode. The competitive multiplayer
mode will feature around 20 maps.


Posted alongside the information are a number of screenshots, which you can check out over in Kotaku's gallery

The Modern Warfare 3 Files: Exclusive First Details on the Biggest Game of 2011 Call of Duty: Modern Warfare 3 is coming Nov. 8, 2011, Kotaku has learned, delivering with it mammoth battles that engulf a dozen cities around the world including New York, Paris and London. Multiple sources have shared details of the game's story, art, sounds and game modes with Kotaku, noting that the game will reshape the landscape of the Call of Duty franchise, bringing an impressive number of eclectic settings, deep multiplayer gaming and a story that ties up nearly all loose ends from previous titles, including the final moments of key figures in the series' history. While we haven't seen the game in action ourselves, we've gone to great lengths to nail down as much as possible the veracity of our sources. We believe that the imagery and chief details are accurate. That doesn't mean things can't change before release, but this appears to be a full run down of where Infinity Ward, Sledgehammer Games and Raven Software is on Modern Warfare 3 as they add the final polishing touches. The game opens moments after the cliffhanger ending of Modern Warfare 2 with the U.S. struggling to stave off a surprise Russian attack. The single-player campaign will ping-pong players around the world as they take on the multiple throwaway roles as a Russian Federal Protective Services agent, SAS Operative, tank gunner, and AC-130 gunner as well as key characters from previous installments and new recurring characters. The game will feature about 15 missions, kicking off with the invasion of Manhattan by a Russian force and wrapping up with a final encounter in Dubai. The plot, as described, seems to be keeping with developer Infinity Ward's habit of delivering complex, short sequences punctuated by lots of gunfire and scene changes. The game also has players take control of several vehicles, returning gamers to the AC-130 gunship as a gunner and plopping them down in a tank as part of a U.S. Armored Division. The single-player campaign, which appears to wrap up most of the unanswered questions and character fates of the first two Modern Warfare titles, also introduces new characters who appear to be destined for future Modern Warfare games, especially two Delta Force operatives codenamed "Frost" and "Sandman". Multiplayer in the game returns with a chunky list of playable maps as well as two types of Spec Ops modes: "Survival" and "Mission". Activision, the series' publisher, still hasn't officially unveiled any details about the game, though executives have said that a new Call of Duty game was coming this year. Last year's Call of Duty: Black Ops, developed by Treyarch, sold more than 7 million copies in the first 24 hours and within six weeks reached $1 billion in sales. We've contacted Activision for comment and will update the story when and if they provide reaction. Modern Warfare 3 Multiplayer Features Battles in Brooklyn, Clash in Mogadishu Brian Crecente — Packed with 15 levels set in locations around the world, from Manhattan to the catacombs of Paris, Modern Warfare 3's near-future campaign looks to be an experience that will top anything seen before in a Call of Duty game. Multiplayer, too, seems to be shaping up to be an experience packed with new maps, experiences and ways to game. Sources tell Kotaku that Call of Duty: Modern Warfare 3 will have as many as 20 multiplayer maps, though it's unclear if some will be cut before release or perhaps sold later as expansion packs. The game will also include a powerful mix of mission-based and survival Special Ops modes. While the mission-based levels will be designed like the ones made popular in Modern Warfare 2, we're told, the survival maps will have players fighting until they're overcome by increasingly difficult waves of enemies. While we haven't seen the game in action ourselves, we believe that the imagery is accurate. That doesn't mean things can't change before release.
