Will replays of Virtual Ticket content be available after BlizzCon is over?
Yes! Anyone who purchases a Virtual Ticket will be able to access on-demand replays of the Main and Panel Stage streams for up to two weeks after the end of the event. Replays of the eSports events will also be available for free.
