(SPOILERS AHEAD)
So I heard the last CEA terminal shows the symbol of the Didact, right (I didn’t find it, but I accidentally read a spoiler thread)? He will most likely show up in Halo 4 (in my opinion). Some think he’s the enemy in Halo 4, some say he is not evil. I go with him not being evil(sorry if my English sucks)! Now, I got an amazing idea. In Halo 2 we could play in some missions as the Arbiter. I think that in Halo 4 we will actually have some missions where we play as the Didact, fighting a new race too powerful for Master Chief to handle (maybe the Didact fights the precursors), but yet not so many missions that we forget who the main character is. I think it would be awesome to play the game from the eye of a forerunner. To feel their power. It would just fit perfectly in my opinion!
So, what do you think?
