At the end of Halo 2, the monitor stated that all of the Halos could be controlled from the Ark. It's possible that what was shown in the trailer was the Ark being turned on, and something that big and powerful would probably take a while to fully power up after being dormant for so long. Meanwhile, while it's powering up, MC is racing to the control room to enter the command to shut off all of the Halos; where as the Prophets want to enter the command to activate them all.
