IGN liveblogging Starcraft 2 announcement

Charles Onyett of IGN is in Korea right now liveblogging the Starcraft 2 announcement. Here's what I've pulled out of his hurried updates so far.

• Game is playable (pray for a demo at Blizzcon), but nothing is final.
• Protoss Zealots have their psi blades and shield, along with a new charge ability. There's a new Protoss unit called an Immortal, with a shield that activates when damaged– looks like they're already implementing Paladins then.
• A new Protoss unit called a Stalker can blink around– Blizzard wants Protoss to quickly put an army anywhere on the map.
• Three more new Protoss units: Colossus has long legs and can move quickly, Warprey is a flying unit that does more damage the more it focuses a ray on a target, and a Pheonix can overcharge weapons, but have a cooldown afterwards.
• Zerglings can now become suicide bombs in a kind of rolling form.
• There's a physics system in the game– destroyed units can roll down ramps.
• System can handle at least 100 units at a time, and looks "similar to SC1 – both in unit and map designs." It must be 3D, though. Right?

Still more to come, including hopefully video of the event. An opening cinematic was shown as well– shouldn't be too long before we see that online.
