I wish to point out to those that are concerned with the cost of the virtual ticket just to get the Demon Hunter Sombra skin, fear not as it has been discovered on this page:
At the bottom of this page there is a pinch bit of fine text that reads:
That being said, I still encourage you to purchase the BlizzCon Virtual Ticket if you are a hardcore Blizzard fan. Last year’s Virtual Ticket was amazing with the videos and documentaries and there is no better way to enjoy this celebration short of being there (which I will be there live for the first time this year). The virtual ticket also lets you get first dibs at new merchandise in the Blizzard Gear store, discount on the Goodie Bag (note that live attendees get the Goodie Bag with their live ticket), exclusive access to really cool panels and so much more.
