Gears of War license was/is one of the most successful projects for the current gen. GoW prints money, therefore we should expect more games in the future. Thus, according the latest rumor, Gears of War: Judgment could be the first game in a new trilogy based on the Gears universe.
Apparently this info has been extracted from a CV of one person that has worked on GoW: Jugdment. Please, check it out for yourselves:
In one way or another, Gears will have more games in the horizon. Xbox One must have its own Gears of War; it’s obvious, so much so that Master Chief will have games for many years. I would like to play a Gears of War being underpinned by the Pendulum wars. It would offer a new side for the already known conflict.
Thanks, Softpedia.
