Although it only has one panel this year, I'm really excited for the SC II panel. I'm hoping for at least a tiny preview of the next expansion, Legacy of the Void, since HotS was/is so sick.
Hands down it would have to be the "What's Next" for World of Warcraft. I'm also quite enthusiastic about the hearthstone panels, quite the addictive game. I live about one hour from the Anaheim convention center, and would DEFINITELY use the tickets. Would be a great bonding experience for my best friend and I, who sadly have grown apart over the years as we get older. Thanks Mmo-champ!!!
I would be excited to see all the panels. I was lucky enough to go in 2011 for my first vacation in years and had an amazing time. I especially like all panels on new information about WoW.
