Additional information about the upcoming expansion for World of Warcraft is gradually trickling out, including a new page on the official site about The Nexus, which will be a dungeon with several parts for 5-man and raid groups. There's a lengthy interview with Blizzard staff on MMO Gamer (part 1 and part 2) which confirms that Death Knights will start at level 55, and reveals a little more about how siege engines and other vehicles will work. "The vehicle system, we’re in the process of integrating physics into it. We’ll have a variety of different vehicles, and they’ll have different handling characteristics. You have one-man fast moving Forsaken catapult sort of things, or the lumbering demolisher that packs more of a punch but doesn’t move as quickly or turn as quickly. We have different dynamics like that, we have flying vehicles, kind of like a flying machine that’s light and fast and a bomber aircraft where one guy can drop bombs and the other is flying around." Vehicles will be available in the new Battleground and the Lake Wintergrasp PvP zone. Also making news is the release schedule mentioned in Vivendi's latest quarterly earnings report, which would put the expansion on store shelves in the second half of this year, but I wouldn't rule out the possibility of delays just yet.
