Another wave of beta invites for Heart of the Swarm have been released, confirmed on the b.net forums in a post by one of the community managers:

"A third wave of beta invites was extended today to over 12,000 players. Like last week, this wave include mostly individuals who opted in via the Battle.net Account Management system.

As a quick reminder -- For those of you still looking for an invite here are a few things you can do to increase your chances:
Opt in for the beta using the Battle.net system.
We are not allowed to email you an invitation without your consent.
Play StarCraft II Wings of Liberty.
We are inviting equal numbers of players from each league to join us in the beta and prioritize players who have been playing the game at some point over the last 6 months.
Keep an eye out for community give-aways.
We will do our best to keep you up-to-date on where those are happening via our social media channels (Facebook, Twitter) and here on the forums. In fact...here's one currently being run by Twitch.tv.

Thank you for being passionate about StarCraft! We really do look forward to getting as many people into the beta as possible."

So check your inboxes to see if you were lucky enough to get in! If not, make sure to get involved in the competitions around sc2sea to have a shot at winning a spot in the beta!
