Saturday's developer panels offered something for World of Warcraft players of all types, along with tons of lore and story details for Diablo III and StarCraft II enthusiasts. Here's a quick summary of some of the discussions that took place on the last day of BlizzCon.

World of Warcraft PVP
The developers showed off the new PvP options in Wrath of the Lich King, including the new attack-and-defend-style Strand of the Ancients Battleground and a pair of new PVP Arenas: the Dalaran Sewers (an underground "fight club" featuring a waterfall that turns on and off in the center) and Orgrimmar’s Ring of Valor (complete with dynamic walls of fire). They also discussed the design of Wrath of the Lich King’s open-world PvP zone -- Wintergrasp -- where hundreds of players can hop into siege vehicles, tear down walls, and try to capture the zone's main keep to gain access to unique daily quests and a raid instance.

DVD Production In the first-ever Blizzard DVD/Video Production panel, attendees got to meet several members of the team responsible for the in-game cinematics, Collector's Edition DVDs, and other videos that help define Blizzard's game universes. The panelists discussed their role in several diverse projects, including the trailer for The Black Temple content patch; footage for the "What's Your Game?" television commercials featuring Mr. T, William Shatner, and Verne Troyer; the Emmy-winning "Make Love, Not Warcraft" episode of South Park; and many of the videos BlizzCon attendees saw on the show floor during the convention.

World of Warcraft Dungeons and Raids
PvE-minded Word of Warcraft players got a guided live tour through some of Wrath of the Lich King’s new dungeons and raid encounters, including the Titan-themed 5-person Halls of Lightning and Ahn’kahet: The Old Kingdom, where players will discover the ancient horrors that lie beneath Northrend’s icy surface. The designers also discussed the Chamber of the Aspects raid encounter, an “expandable” fight that lets players choose its difficulty (and reward level) by deciding when to engage certain enemies. The designers also addressed the how and why of the new dual 10-person and 25-person raiding structure for the audience.

StarCraft II Lore
Following yesterday’s revelation that the ambitious story of StarCraft II would span a trilogy of games (see Friday's Developer Panel Roundup for details), Blizzard’s lorekeepers set the stage for the terran campaign by discussing several characters who will figure prominently in Jim Raynor’s adventure, including newcomer Tosh, Matt Horner, Valerian Mengsk (son of Arcturus Mengsk from the original StarCraft), and Tychus Findlay, who players first met in the original StarCraft II cinematic.

World of Warcraft Open Q and A
World of Warcraft panels at BlizzCon always conclude with some audience Q and A time -- but it always seems like there's never enough. That's why at this year's convention, the developers took the stage for a panel devoted exclusively to answering audience inquiries. For a full hour, attendees in the packed main hall asked about Achievement rewards, new in-game storytelling techniques, class balance, randomized daily quests, druid form art assets, and much more.

Diablo III Lore and Art
Diablo III's world-builders discussed how they’re bringing the history and culture of Sanctuary’s different cities and citizens to the forefront for the sequel. The designers also demonstrated how each of the different classes’ personalities, from barbarian to wizard, will affect conversations with NPCs. After that, the art team took the stage to discuss the look of Diablo III and the process of reinventing Sanctuary in light of today’s 3D technology -- and showed off some of the over-the-top devastation that powerful players and monsters can wreak in the game’s destructible environments.

Blizzard Cinematics
In the final panel of the day, audience members got a chance to talk with the Blizzard Cinematics team and get a behind-the-scenes look at how Blizzard makes the pre-rendered movies and trailers for its games. The team walked through the process of making the recently released Wrath of the Lich King opening cinematic, from designing the great frost wyrm in the trailer to modeling and animating the roughly 15,000 undead soldiers in Arthas' army.
