Today, Blizzard detailed the many new units that will show up in Starcraft II: Heart of the Swarm. Rather than just describing a bunch of abilities and units, they decided to also show them in action in this Protoss vs Zerg match.
Over the course of the 24-minute match, you can see many (maybe all?) of the new Protoss and Zerg units in action, and Rob Simpson and Day's shoutcasting helps keep track of what you're seeing.
Man, just when I was starting to get tired of Diablo III, Blizzard reminds me how much I like StarCraft II. Well played.
