Blizzard announced the highly anticipated launch of LotV's closed beta starting on March 31st! They released a teaser video detailing the multiplayer features they'll be testing in the beta featuring Archon Mode, resource changes, warp-jumping Battlecruisers, the return of the Lurker, and a brand new Protoss unit called the Adept! A full preview of the changes can be found here.

Concerned about the Cyclone's continued existence, but here's hoping I get in at some point. Blizzard tend to like to never give me beta keys for anything I'm signed up for.

@bollard: I heard rumors that a laaarge amount of keys will be given out to active sc2 players. So stoked.
