#3, I still feel that if you need a unit that does extra damage against armored units, Marauders with stim are still a way better option. They are much smaller too so you fit more of them in a concave and cheaper too.

Locusts do have a duration and despawn slower than broodlings. they also have much more life and attack damage. I don't actually remember at what tech you can spawn Swarm Hosts, but I think it's Lair, sadly I didn't get a chance to try the multiplayer again today. For the Viper you need the infestor building, but again any of this can change before the HotS beta.

I did see those two and Fantasy as well. They attended the GSL finals and were swarmed by fans for autographs in between the matches lol. They left early tho, right after the 4th game if I remember correctly. They actually had special seating with other VIPs like GOMtv CEO and Blizzard CEO, Mike Morhaime. It was a good finals.
