eriously guys, since it's Tomas Wiborgh, half of the so called "information" was just not information about the game. So I'll just type the "Halo 3-stuff".
Oh, and please don't bother my english, since it's quite obvious that I'm a Swede. I still hope it's readable, though.

HALO'S SECRETS
The biggest, prettiest and hardest spacewar is about to end during 2007.
At E3 in summer, we got to see Master Chief in his suit. Just a month ago,
we got a personal meeting in Bungies HQ. We are LEVEL (the magazine), we have
played Halo 3 before anyone else.


After weeks of emailcorrespondence with letters, we finally made it to
Seattle. Even though I didn't know what we were about to see, it was still exciting.
Of course, it had to do with Halo 3 but we weren't too sure. But we shouldn't have doubted it.

Welcome to Bungie
We get to meet Brian Jarrard, the man with the jacket. The guard looks at me and closes
the doors behind us. The first thing we meet is Bungies own sodamachine. Master Chief
sells his soul for Mountain Dew. Behind the right door of it, is Halo 3 being developed in.
It looks like Nasa in there, one huge room with lots of screens and papers.
The left door was just about to open itself, and we were very excited.

The cards on the table
When the door finally opens up, the Halo-loggo starts spinning around on a big TV.
Xbox 360's are just next to it and huge headsets. Sometimes, it felt that I was really
about to play Halo 3. That feeling felt good, inside. After a couple of seconds,
I'm sitting there with my Xbox 360 wireless controller in my hands. I get to meet
a well-known greensuited man with new weapons.

If you're used to the controls in previous Halo-games, Halo 3 won't be hard at all to find
it "confortable". Bungie has actually been working on a new concept, where the player represents
a perspective of the handcontrollers back (?). With the shoulderbuttons, you reload.
This is like a complete version of dual-weilding. You also get to reload your weapons
individually, that way, you get more tactic-aspect during the war. It's about life and death.

Detailfeeling
Before anything is said, Jaime Griesemer said that the multiplayer-part of Halo 2 was good...
in the begining. It was popular but definitely not perfect. One of the problems were
"spawning weapons". In Halo, we had the old version of our
Assault Rifle, which seriously gave an impression like "worthless".
We also had the revolver, which was a bit powerful.
Nothing was spectacular, and we just had too many SMG-weapons.
When we started developing Halo 3, we sat down and thought of many new ideas.

New Toys
I don't think I'll spoil much if I say that Brutes will have a huge role in Halo 3. They will be huge, and yes, hairy too. With massive weapons.
The weapon which is rotating on the screen while Jaime talks is equipped with long, knives and their ammunition contains of deadly spikes.
At the moment, we call them "Spiker". On the top of that, Bungie introduces the new spikegrenades, which can be set on walls or roofs.
Next stage is Highground, which reminds us of Zanzibar. Me and my team cooperates with each other, while the enemy has its camp on the beach.
Our warthog stands right next to me, so I'm safe when it comes to defending.

Welcome Home
The third and laste stage has the name "Valhalla". It's like paradise, but better.
Water, trees, mountains, it's the stage I've been dreaming about. All the pretty stages in Halo,
but now on updated hardware. Valhalla is our new Blood Gulch, sais Jaime Griesemer. It's terrain is very
vary(ed..?). I get to know the new vehicle, a Mongoose. It sounds like a motorcyckle, and it's perfect
to use in handy on huge stages like this one. There's also the new transportmethod named Man Cannon.
I jump of my Mongoose and jump in the cannon. Well, I fly. I fly in the air and I get to see hundreads of meetres from above.
I see lots of war under me. X-button will do something special.

The End
Before you go home today, we have something to show you, said Brian Jarrard. It's not
much, but I know that it's been anticipated. You're just about to see the first singleplayer part of Halo 3.
Everything you see is 100 % true, and you get to see it one time.
The lights were off and the sequence loaded. We see a city, full of explosions and motions.
Soldiers shoots covenants. Grenades fly everywhere. Master Chief gets bullets on him, while his shield
starts to blink very weird.

It's over. That was it.

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.
*Nail Grenade: Sticks on walls and emits nails into the air.

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."

Apparently, reloading is done with the bumpers and the X button has some game changing new functionality that Bungie isn't revealing. You can reload each weapon individually.

Your secondary is always visible at your back.

No bots in MP.

There are also many more plot twists than in either of the other games.

Also, there is going to be made a Legendary edition:

Legendary Edition

The CE will be called “Legendary Edition” and is a replica of Master Chief’s helmet complete with four DVD discs. The first disc will be the game disc, the second will contain documentaries and developer comments, the third disc is all about the spin-off material that has been created (Red vs. Blue, Spark of Life etc) and the last disc will contain all of the cut scenes from Halo 1 to 3 in HD.
