We actually hadn't heard that Gears of War 3 was announced -- wasn't Cliff Bleszinski's big reveal bumped to Monday? -- but thanks to the marvels of modern technology and inattentive switch flippers, our Xbox 360 has brought us up to speed. The menu item (shown above) in the Xbox Spotlight channel doesn't lead to any further information, but does seem to confirm that "the epic story concludes April 2011." [Update: It's gone now.]
Oh no, all our GoW trilogies are coming to an end!
