The site is also carrying a shot of the game, albeit apparently from an old build of the game, showing Marcus in the main window with the player in a window bottom right of the screen.
Kotaku claims a demo of the game re-used elements, like assets and events, from Gears of War 2.
In November, Epic design boss Cliff Bleszinski said a Gears reveal at the Spike VGAs would be "not what you're expecting".
But just a few hours before the event itself, Major Nelson confirmed the showing had been canceled until sometime this year at least.
Epic also trademarked something known as Gears of War: Exile recently.
