I think by the time it hits market and is completely finished and polished we can expect visuals on par with the likes of Killzone 2. I mean the engine is a completely ground up built compared to the last two Halo games.
Big factor for me and a bunch of others is that Bungie is not going to forget it's roots and give us amazing 4 player split-screen and guest support online (remembering we do have real friends, and they like to play online too!), Not to mention stellar 4+ player co-op. I'm excited at the thought of a game close to the graphic scale of Killzone 2 but also to incorporate these heavily missed features lacking in Killzone 2 or many other larger scale shooters for that matter.
