In the Gearbox Forum they mentioned Aliens: CM when they announced the Community Day (

This is the announcement:
Open to all, Gearbox Community Day is a celebration of our awesome fans, our history as a studio, the launch of Duke Nukem Forever, and of what lies ahead for Gearbox.
This will be your chance to play Duke Nukem Forever alongside the Gearbox crew before the game is released in North America. You'll get to hear the stories and meet the people behind some of Gearbox's biggest games, including Borderlands, Brothers in Arms,
Aliens: Colonial Marines and more!
Better yet, you'll get to experience the first public unveiling of never-before-seen materials by Gearbox.
