This 24th in the media day, Blizzard announced their marketing plans with Korean Air. They wrapped two Korean Air planes with Film and Paint of Starcraft 2 Illustrations, and these planes will operate both inside Korea and planes flying to America, europe, and such.
Blizzard says they're happy, and they want this to be an huge opportunity to let all the gamers know about the Starcraft World's characters.
Korean Air states that this is part of a new history, and that through this they could stand in the middle of revolution, and how they're planting seeds to the younger generation.
Furthermore, Blizzard announced their partnership with Lotteria (Hamburger chain in Korea) and nVidia.
They seem to all be just advertising campaigns.
