Isn't that level in Halo 2?
The first picture.

Yeah it looks like Zanzibar, but it isn't. Its'just a similiar level.

The pics are not bad but the SM will be looking a lot better!

If multiplayer has weaker graphics...I would like to see more single player. I want to see what Halo 3 can really look like...

 Wow... I don't own Halo and only ever played Halo 1's demo on the PC and a bit of Halo 2 at work..  I recognized that as well... LOL...  damn I hated that level...  Some project manager kept kicking the crap outta me on that level..  Suprisingly I went from being the worst at the game to being one of the best pretty quickly...  which was sad... real sad...  

Looking good

I want to see single player too, E3 they will reveal the first single player level(s) and they will be playable.

That is when we will know what Halo 3 really looks like.

If I was a guessing man, I would say single player will likely have effects turned up to high, as compared to multiplayer. I wouldn't expect a dramatic difference in graphics, but it should be noticeable. Does anyone know if it runs 30/60 fps or 1080p native?

Looking good.

And I like the remodeled Zanzibar. It's like what it was in the past before it was destroyed I guess is a way of looking at it.

Great, now if only they could make a 360 that didn't melt when it ran this game? Not meaning to be a troll... But i'm kinda waiting to buy a 360 until they get over the hardware problems.
