from what i can tell..it is the worst part of the game..the demo hasnt showed anything really new to it..but i think it was a time constraint that is why its not improved very much this year..i bet next year they'll change it.
This is what im hoping for.. a commentary pak in DLC..i'd pay for it, seriously but the commentary from what i've hard and seen thru other impressiosn dont really ruin the overall atmosphere..its just the game would be even better with good commentary.
