A couple of updates to the official StarCraft 2 site today:

1) New movies have been added to the movies section.

These show the Blizzard event in Korea. A low quality version of the event has already been available on Youtube. These are higher quality videos of the presentation:

• Introduction by Mike Morhaime, president and cofounder of Blizzard Entertainment
• Blizzard Retrospective, a look at Blizzard’s history
• Cinematic Trailer Introduction by Mike Morhaime
• Gameplay Demonstration narrated by StarCraft II lead designer Dustin Browder
• Artwork Trailer Introduction by Dustin Browder

The Blizzard Retrospective is the only video that actually benefits from a higher quality version, since it features games and not just talking heads. Give it a go.

2) Previously revealed Protoss units have received updates.

Their pages now contain in game audio responses. Check out the updated pages for the Zealot, Immortal, Stalker, Phoenix, and Colossus.
