SC2 Heart of the Swarm Release Date?
NewEgg shows a ship date of Dec 31st, 2012:
This is likely just a placeholder date as there is no way Blizzard is going to release a game immediately after the holiday shopping season. So it will either be released significantly earlier or significantly later than that IMHO. I will update this page once I find a definitive release date and if you have any additional info feel free to leave a comment
