I find it strange how they have said we find out the fate of Burke even though we already saw his fate in the Directors cut. And if they are not using the directors cut as cannon, then how come they put in the sentry turrets reading 0 on the ammo counter?
Also I think Hicks will be alive. They wouldn't have bothered getting him just to do voice logs. With all that talk about scratching itches, killing off Hicks has to be one of the itches they were talking about.
