Blizzard Entertainment deployed beta build 18594 today adding a new intro music theme which plays at the loading screen.
At the moment of this posting servers continue to be offline. A few hours ago, I reported there was a blackout that affected not only Blizzard Entertainment Irvine Campus, but a large area in South California due to a fire at an electrical power substation. The SCE restored power around 4am EST / midnight (Pacific).
Servers will go online as soon as Blizzard staff gets back to the office, and maintenance is completed. This patch will trigger a character wipe, so beta testers will have to start testing and level from scratch. More sightings soon.
