I'm mostly looking forward to the World of Warcraft - What's Next panel, as most other people probably are, but also looking forward to the World of Warcraft – Gameplay and Systems Deep Dive, it's always fun to learn abit more about the behind the scenes thinking of the devs
Codecraft: Under the Hood with Blizzard Engineering.
I imagine it'll be super fuckan neat, like with the Art panel in years past. Or the music. Heck I still remember the Cinematics, them filmning the guy coming out of the water with fake swords to stand in for Varian in the Legion cinematic.
