In the Halo 3 announcement trailer displayed at E3 2006, Cortana makes a brief appearance with some key signs of rampancy. Her image appears in brief "flickers," and her voice has a grainy distortion to it. The corruption of images was also used extensively in Marathon as the AIs progressed through their rampancy. Also, her speech patterns, including phrases such as "I have defied gods and demons" and "I know you; your past, your future" resemble the prophetic megalomania demonstrated by Durandal. In the Halo 3 trailer it appears that the Gravemind may have lead Cortana to this.
In the Halo 3 storyboard pictures, there is a single picture of what looks to be Cortana in great distress.
