A new announcement is promised, too
Blizzard has announced that it will hold a Hearthstone event live at the Folsom Street foundry in San Francisco California next week. It starts at 2:30 PM PST on July 22, and will feature matches, developer access, and a “momentous announcement.”
If you want to attend, checking the Facebook event page is probably a good idea to get up to the date plans, and apparently, space is limited. This sounds like a nice little get together if you ask me.
