Halo Reach Trailer will be in game engine...

"@DarkWaterClone our cinematics run real time in our game engine, they're not outsourced CG"
The Bungie tweet say's it all really, the Halo Reach trailer will use the in game resources of the game itself, just like the reveal for Halo 3 did.

Which means this dude was wrong about the trailer not being CG. I dunno what you might be calling the opening cinematic of Halo Reach rendered by in the in game engine, but I'd call it CG - i.e. computer generated. What else has he been wrong about?

How bad are you looking forward to the trailer!!!
