The World of Warcraft: Battle for Azeroth Collector’s Edition Pre-orders are officially open. Expect the item to ship on August 14, 2018.
The Battle for Azeroth CE contains a lot of digital cosmetics, a new novella titled Elegy & Good War double-side book. I was told at PAX East by a Blizzard representative that there is no CD, but you will get the Soundtracks in the CE as a digital download.
