PC Gamer has a good interview with Tim Morton about Starcraft II: Legacy of the Void. They talk about the new Archon mode as well as new game units such as the Zerg Lurker. They cover many of the details that were already discussed, but since it's fun to keep talking about Legacy of the Void and consume every bit of information it's fun watching interviews like this.

That said, Tim mentioned that they are going to launch the beta in the first half of 2015 and I image the game will come out some time thereafter. Here's to a speedy 2015 launch!
