Not much Wrath information was announced at the WWI last month and we may see more at this year's BlizzCon, but with the beta in full swing and Blizzard close to launching Wrath, there may not be too many surprises left to announce at the event. We'll possibly see some kind of opening cinematic and probably talk of what new content is planned shortly after launch.
Still, there will be much to see and do at BlizzCon as we expect their usual blend of contests, hands-on demo stations, dev panels, goodie bags, tournaments and probably some big announcements for Starcraft 2 and Diablo 3. One thing BlizzCon won't have is livestreaming over the net. For those who can't make it, DirectTV will be livestreaming the convention as a pay per view event.
