Wie im Blizzardforum berichtet wird vom Blizzard Mitarbeiter Lylirra steht die erneute Beta Öffnung kurz bevor, und soll bis zum 19 Juli auch geöffnet bleiben. Ebenfalls teilt Lylirra mit dass alle Statistiken zurück gesetzt wurden. Es muss also jeder Beta User nochmals von vorne beginnen. Des Weiteren sind die Patch Notes zu Patch 16 aufgetaucht. Hierbei geht es im grossen und ganzen um ein paar Zerg Änderungen, und Anpassungen am System selbst.

The second phase of the StarCraft II: Wings of Liberty beta test is now underway. We're delighted to invite you back to the battlefield and hope that you will join us through July 19 for more terran, protoss, and zerg action.
As stated previously, all data from beta phase one has been reset. This includes characters, match history, ladder rankings, and achievements. Beta participants will therefore need to recreate their characters and, if joining matchmaking games, complete a new series of placement matches.
We thank you for all the feedback you provided during phase one and are excited to hear about more of your experiences in phase two. Welcome back to beta, and we'll see you on Battle.net!
