Blizzard Korea just posted a video of cosplayers who attended G-Star 2012 in Busan, Korea. Among the cosplayers are Diablo III (Leah, Demon Hunter, Monk, Witch Doctor), StarCraft II (Nova) and World of Warcraft (Chen Stormstout, Murlocs, Lady Sylvanas Windrunner, and Jaina Proudmoore).

Can’t decided on which was the best, but certainly enjoyed the Witch Doctor dancing PSY Gangnam Style — cracked me up!
