"This summer we will be opening up external beta testing, and while we haven't announced a release date yet, this phase will also signal the final stretch [of development on the game]," said Morhaime during today's Activision Blizzard conference call. Signups for the beta officially opened yesterday, with users able to opt-in to the test by way of their Battle.net profiles. The test will focus on the multiplayer mode, featuring all three of the title's races and several maps.

"Our priority now is completing the core game," added Morhaime. "Once that is complete, our focus will shift [to the two expansions]."
