How quickly we forget our history.....Killzone 2 E3 2005?

Haha, you are so bias in your defense of something which does not need to be defended. 6months after halo 4 I do not expect a in-game trailer. CGI would make sense and they've done that before. But seeing as we're entering a generation where the lines between CGI and in-game truly are supposed to become blurred, I think a in-engine demonstration of how next gen Halo will look like would be far more fitting. I say disguised as a teaser because I think it will be more conceptual, designed to highlight possibilties of the system as opposed to a literall cutscene from the next game.

"CGI would make sense and they've done that before."

No they have not....WTF are you talking about...

CG :Cinematic Gameplay

A cutscene or event scene (sometimes in-game cinematic or in-game movie) is a sequence in a video game over which the player has no or only limited control, breaking up the gameplay and used to advance the plot, strengthen the main character's development, introduce enemy characters, and provide background information, atmosphere, dialogue, and clues. Cutscenes often feature on the fly rendering, using the gameplay graphics to create scripted events.

CGI or FMV:Computer Generated Imagery or Full Motion Video

Cutscenes can also be animated, live action, or pre-rendered computer graphics streamed from a video file. Pre-made videos used in video games (either during cutscenes or during the gameplay itself) are referred to as "full motion videos" or "FMVs". Other cutscenes can simply just be text interludes with speech bubbles over the characters' faces.

What bias exactly? No one cares what you expect or what would make sense for you because we will see in a few days who is right. Also keep in mind that it is rumored that 343 has two teams working on Halo-games which leads to different conclusions for me. But of course this is biased where your opinion of course isn't, right?
