It looks pretty good so far, but I'll make up my mind when the demo comes out.
Just looked on Wikipedia..."The title is scheduled to ship before the end of Activision's 2009 fiscal year for PC, PlayStation 3, Wii, and Xbox 360.[3] It is set in the Pacific theater and Eastern front of World War II."

-Swimming in multiplayer and singleplayer modes
-Based on the Infinity Ward COD4 engine (Should be a similar game play then)
-Flamethrower with the ability to set objects in the game on fire, where the fire will be able to propagate
-Bullets will be able to cut through thin wood and make large enough holes to climb through
