Call of Duty: World at War would be launched on November 11, 2008. This means Call of Duty will be launched before the Conduit. Now Call of Duty is releasing a multiplayer beta on Xbox 360 and PC in October. Hence people looking for the game on Xbox can preorder at GameStop.
Nintendo is helping its Wii owners to play as a shooter before the Conduit enters their life. Unfortunately PS3 and Wii owners do not have the access to other platforms so a multiplayer is difficult to pass up. For all of them, it is best that they see the preview of the game and wait for the game to release.
