The trademark applications include "Gears of War: Exile" and a proposed logo. The trademark was filed for use with t-shirts, a "series of computer game hint books and instruction manuals," and "video game software," which means we're most likely looking at a game and not simply another novel or comic book.
In late November, Cliff Bleszinski, Epic Games' design director, promised a Gears of War-related announcement for the 2010 Video Game Awards. The announcement was pushed to 2011 on the day of the show. The project was rumored to be a Kinect-enabled Gears of War title, but there has been no confirmation from Epic Games or Microsoft.
Epic is currently developing Gears of War 3 for the Xbox 360 and will release it this fall.
