There's a good chance no.

: be a fantastic egg... and remember the Jackal Phalanx!)

I'd rather forget the jackal phalanx. There's a reason they don't do that in the games, and it has nothing to do with AI being a hard problem to solve. The E3 2003 demo itself answered why it's stupid a few seconds after it showed up, and I saw the warthog coming well before it entered on-screen.

: It also kind of bothers me that Halo 2 will look better than 1, 3 or 4

It probably won't be a huge leap. There are some things I noticed that are graphically nice (like some first-person self shadowing that isn't total garbage), but overall a lot of people have thought it looks sort of like a 360 game with high-resolution textures.

Speaking of which, there's the question of art style...

: Final Thought... I don't see anyone else mentioning it... But the Chief's
: armor looks... too monotone... and his visor looks yellow... In truth...
: While everything else looks better... (though many things are TOO bright
: compared to the original, especially the aesthetic change in Armour
: color!) I prefer the updated Chief. The suit just looks... TOO clean and
: crisp compared to the original... Though I reserve final judgment for
: actual playthroughs!

...It's got lots of flatly-textured surfaces, lit by a hard-edged high-contrast lightmap. It looks pastel and blown out in bright areas, and muddy in dark areas. It has a sort of "Halo 4 forge map" look to it.

Though I appreciate the use of lots of transparency effects, the game is currently usually lots of not-quite-great-looking sometimes-too-bit over-lit transparencies.
