there is absolutely no information here as to what actually happened during Blizzcon 2010. This makes me conlude that either the event never took place, or none of the editors went or have seen videos of it.
No editors went, and there's very little info on StarCraft from there anyway. Blizzard hasn't even given any (official) previews of Heart of the Swarm. Info from videos was placed in relevant articles (eg the canon discussion). PSH aka Kimera 757 (talk) contribs) 23:23, December 10, 2010 (UTC)
