Kotaku writes; "Every year a new slogan is announced for the Tokyo Game Show, held in Chiba, Japan. After that, a poster is unveiled. This is this year's.
The official translation of this year's slogan is "Game, it's so energetic!" (The Japanese word "genki" has various meanings - plug in whichever you like.)
TGS 2009 runs from September 24 to September 27 with the first two days being business days."
