Patch 5.4: The Siege of Orgrimmar is set to release in North America on September 10. Looks like they are getting ready to finish up this expansion with a set

“Garrosh Hellscream’s treacherous excavation of the Vale of Eternal Blossoms has finished with sinister results — not just for Pandaria, but for all Azeroth.

In a compound beneath Ragefire Chasm, Garrosh has infused his followers — the ‘true Horde’ — with the pilfered essence of the Old God Y’shaarj. With the power of a primordial world-twisting force at his command, Garrosh can rebuild the Horde in his image: strong, obedient, and, most importantly, ‘pure’.

Vol’jin’s attempts to lead Horde rebels into the capital of Orgrimmar haven’t gone unnoticed — and the mightiest heroes of the Alliance have stepped in to siege one of their enemies’ most prized cities. Will the Alliance be content with overthrowing a despot, or will they crush the Horde at one of the most vulnerable points in its history?”

Pretty epic! Check out this fancy patch trailer too!
