Personally I think it's Bungie showing their traditional 'preview' colours here. Short, Sweet Cut-scene of what is to come.
From what I gather (fumbling around the Bungie website
) the graphics shown are all in-engine (this is said on the download page for the trailer) and that scene is indeed the ruins of New Mombassa. So basically it's showing the aftermath from the end of the second installment.
As far as gameplay goes, Halo2 never added that much over Halo. I very much doubt the whole awe-winning gameplay is going to be messed with even slightly. We'll probably be looking at something more along the lines of more war, more master chief, and best of all more of that lush storyline that had me glued to an xbox360 all last week playing Halo2 co-op with a few mates.
As for the rest of E3, I'd suggest checking out the other forum threads
