Why is there a need to give the new Halo a title?
All other Halos before, except Halo: Combat Evolved and Halo 3: ODST, didn't have one and looked fine. I think it would look better without a title. So there's not exploit or hint. Keep the continuity of the what the game hides. Titles for titles are only good for a story that branches off into a different story. Like, if there's going to be a Halo 4: whatever that played the roll of whoever. I would rather see that with a title than the next expansion fo the actually story.
