During Microsoft’s time at the E3 2012 Conference, they revealed that Gears of War: Judgement is due to arrive later in 2013. A short trailer was shown before any information was heard of, and it proved insightful to say the least.
Epic Games are cooperating with developer People Can Fly on the Gears of War “prequel” so that they can focus on several other titles in development simultaneously. It should still be effective to work against time.
We can expect more information of the game to arrive soon, especially with more specifics towards a release date.
