Thats a link to the Halo 3 page of Bungie, and its shows the informaton about it.
Here is the last paragraph:
"The Master Chief's AI companion Cortana is still trapped in the clutches of the Gravemind - a horrifying Flood intelligence, and a civil war is raging in the heart of the Covenant. This is how the world ends..."
Emphasis on the italic 'This.' IMO, this maybe a clue from Bungie that it is not the Halos that finish the World, but maybe the Covenant Civil War, or most probably the fact that 'Cortana is still trapped in the clutches of the Gravemind'.
To me, this proves that Cortana is not rampant, and that she has been captured, and maybe being controlled by Gravemind at the most.
So, because she has been captured, this may lead Gravemind to the locaton of Earth, and because he controls the flood, he can send them there, and that is the way the world ends, and the hands (or tentacle things) of the flood.
ps-if this is a repost, then sorry.
