It's got tons of information. Like the maps Epitah, Shrine, Last Resort, and a secret map. They also talk about a new equipment, the radar jammer.
Or, look at the low quality scans in this article.

Weapons
Magnum - The Magnum is much improved since
Halo 2, dishing out slower, more punishing shots. But it's still not back to Halo 1 strength, as the clip currently carries just eight rounds and you can't zoom in. Still a nice, precise choice for dual-wield combos.

Energy Sword - The infamous Sword gets two tweaks aimed at balancing its overwhelming power. One change is a brief weapon-switch delay. The second adjustment is more controversial: the Energy Sword now has an ammo meter that depletes with each attack, which keeps players from hoarding it indefinitely.

Vehicles
Wraith - The lumbering Covenant Wraith returns with a new player-operated secondary turret. It's helpful for driving off boarding attempts.

Brute Chopper - This ugly, jagged Brute Chopper looks like something Firefly's Reavers might drive into battle. Its twin cannons nad heavy, blade-like chassis can pulverize lesser vehicles in a nanosecond.

Equipment
Radar Jammer - Hurl this item into a fight and watch as chaos and confusion engulf friend and foe alike. The jammer scrambles the radar of all nearby players and triggers disco-like light flashes to further disorient your prey.

Maps
Shrine - A UNSC battle cruiser looms menacingly over Shrine's sprawling sand dunes. Shrine is the largest map ever to appear in a Halo
game, so Bungie put a key emphasis on vehicle-on-vehicle combat. Shrine has few ties to older Halo 2 maps, but its massive size recalls Relic.

Epitaph - Epitaph is an arcane Forerunner cathedral-like structure that towers above the surrounding wasteland. The central killing floor is crisscrossed with elevated walkways, exterior hallways, and lifts. It's a spiritual successor to Halo 2 maps like Colossus, Gemini, and Midship.

Last Resort - Zanzibar, one of Halo 2's most beloved maps, has been rebuilt and rechristened Last Resort for
Halo 3. This industrial site is almost twice as big, with a less cluttered internal layout and more paths into the flag room.
Secret Map - Bungie sneakily sent us two mysterious concept paintings labeled only as "Work in Progress Map." We see the icey motif and pray for a new Lockout, but only Bungie knows the truth.

Customization
Create a Spartan:
Tired of staring at Master Chief's ugly mug? Halo 3's online mode offers new armor permutations that allow players to customize their personas from head to toe. Will the Covenant Elite player
models be eligible for similar upgrades? Only Bungie knows.
