Hearthstone's first expansion, Curse of Naxxramas, is coming next week, Blizzard announced today. The update will go live on Tuesday, July 22 for PC, Mac, and iPad, so says the Hearthstone Blog.
As previously reported, the first wing of Naxxramas, the "Arachnid Quarter," will be free as long as you download it during the launch period. Four more wings will follow, priced at 700 gold or $6.99 apiece. If you buy them all as a bundle, it will be $19.99 for the set of four, or $24.99 if you miss out on the launch event and have to pay for all five.
While you wait, check out some more thoughts on how Naxxramas could change the dynamic of Hearthstone as we know it.
