It is very likely that the flood will be on earth in H3. When Cortana speaks her voice is distorted because there is a hint of Gravemine speaking. It would make alot of sense if it was Gravemine speaking too. In the end of H2 Cortana is in the clutches of Gravemine. He probaly hacked Cortana so that he could find Earth. He may have read other files in Cortana like the MC's past. That is why he says in the trailor "I know you, your past, your future." Meaning that the chief will go to the Arch to finish what he had started, ending the war and stopping the flood. Also in the end he says "This is the way the world ends." It could be by the flood, the covenant, or something that has to do with the Arch. The flood will probaly come by the covenant ships they had infected. They were isolated on the Halos to starve to death but then the humans and covenant found them. They need more food to stay alive. Why not go to the sorce? The covenant holy city and Earth. Billions of humans live there. The flood could thive there and they plan on doing just that!
