they said the flood wouldn't be in halo 4 but they didn't say anything about the flood in halo 5 or 6. i think it would add to the old halo feel if the flood return as annoying as they are. plus this trilogy is about humanidy taking control of the mantle by ending the storm rebellion and eliminating ALL of the flood because there are still flood spores in each halo rings. i also wounder how they wou;d look in the next gen graphics, that bing it is going to be on the new xbox with better graphics and more contant. As for the arbiter, I would love for his return, definantly bring back old memories. I know its a new trilogy and all but it in the same universe besides they killed cortana one of the main characters so we need alother familer face. If the arbiter returns i and the rest of the communty would be happy but i also would be alittle scared because 343i is know to kill of there main characters, arby might die because halo 5 is suposed to be "darker" than halo 4. I honestly don't know why 343i is trying to have a dark storyline. I don't like depressing games, there just sad to play knowing your favorite character is going to die. they should make it like halo ce or halo 2 were the storyline is a little more happyer but still bad*ss.
