World of Warcraft: Wrath of the Lich King Previews

The weekend comes to a close with two more previews of Blizzard's World of Warcraft: Wrath of the Lich King expansion pack. The first is at Game Informer:
The PvP game has been improved, with the addition of siege weapons. And what use would a siege be without something to break? Blizzard says players will be able to drive these monstrous machines and destroy their opponents' buildings in a brand-new battleground. This mode will support 15 on a side, and a game should take between 30-40 minutes to complete.

And the other is at Yahoo! Games:
The Lich King Arthas is the primary impetus behind going to Northrend, and you'll get to raid and fight against him. Kaplan says he's bad about breaking crowd control, though, so don't group with him.
