Looks absolutely fantastic.

Also, a little something from Bungie's Twitter:

@geoffkeighley GameTrailers is sayin' our hot new trailer is CG? Thanks for the compliment, but nope...that's all in engine!

by freaking god, i just jumped on twitter (about to go to bed) and saw that as well.... this is gonna have a slight graphical advantage of halo 3 lol

It looks puuuuurrrrrrdddddyyyy

OMG!!!

That looks fantastic.  

its obviously ingame, i don't know how anyone thought otherwise,it looks great, that dogtag part has something to do about the books right?

LOL. Shane from gametrailers said this game looks outdated...

With graphics looking like that and if the campaign has the variety of Halo 3 campaign, and weight and emotion of ODST...this is going to be the best possible farewell Bungie can give Halo fans.

shane from game trailers is... WRONG

LOL @ Shaney boy.

Halo Reach is the most impressive game engine Ive seen to date.

It's Graphics are of high quality. Just look at it. But the most impressive thing, is it looks like that and has the biggest playable areas on console gaming as well as 60 enemies onscreen. 

Bungie please lease this engine to other devs on 360. It quite simply is brilliant. Other devs should follow more. And not concentrate on the most realistic look whilst sacrificing huge levels and enemy numbers.

GOTY 2010.

PS LOL at GT saying it was CGI?

People are obviously shocked how good it looks with all those high quality characters onscreen at once. 

Go Bungie.

Go Bungie! Hope that game sells more than Mw2 !
