Blizzard dropped the news today that Heart of the Swarm will enter multiplayer beta "very soon." I enjoy the Zerg quite a bit and am looking forward to the single player game. Wings of Liberty was very well done and I anticipate Heart of the Swarm to be just as good or better! I know, perhaps my expectations are too high for a post Diablo 3 Blizzard? I certainly hope not.

Relevant bits from the blog:

"We are preparing to invite testers for the Heart of the Swarm beta very soon! To be clear, this test will be for the multiplayer experience only. We will begin with a select group, including many players who assisted us in testing Patch 1.5, as well as some pro-gamers and press. Over time, we will add more and more testers into the mix.

If you are interested in participating in the beta test, please make sure you are opted in for beta testing. You can do this by clicking "Beta Profile Settings" under the Account Management section of your Battle.net account. Note that the opt-in doesn't guarantee entry, but gives you a chance at joining the beta test. Also, we'll be working with your favorite fansites and community personalities to give away more entries to the beta test, so keep an eye out for invites coming from the greater StarCraft community over the coming weeks.
"

Really hoping to get in the beta to try the new units!
