Several magazines have Halo 3 covers this month, a few European ones and EGM.
The first subscriptions are hitting mailboxes.
This is what we have so far.
"Just got LEVEL (swedish gaming mag) in the mailbox..
Really nice Halo 3 cover, and a 10-page or so article on the game, with lots of (multiplayer) pictures.
I haven't read the whole article yet but they reveal 2 new weapons and 1 new veichle, and also a "Legendary Edition" of the game.
The "legendary edition" is sort of a "special-special-edition" that consists of a Full-size replica of the Master Chiefs helmet that contains 4 DVDs with material.
1= The Game
2=Various documentaries and audio commentary
3=Spinoffs such as "Red vs Blue" and "Spark of Life"
4= ALL the cutscenes from all three games in Hi-def
Oh, the game looks great btw"
Now that's how you make a good package....

Here's hoping for scans soon.
Update:
"To be honest I haven't seen much of Resistance so I can't really say which looks better..all i can say is that Halo 3 looks really good in the pictures (especially the environments) and according to an interview with some Bungie people that is in the mag,

of graphical effects that will be in the final version are not even in this version.
New Weapons:
*Spiker: the weapon of choice for brutes.
*Spartan Laser: An anti-veichle weapon, fires a red laser that pretty much destroys any veichle that is hit.
New Veichle:
*Moongoose: The ATV that was supposed to be in Halo 2. It carries 2 people and it doesn't have any weapons so it's mainly a means of getting from point A to point B as fast as possible."
This will make a lot of people happy.
