On that note, Psy is quoted as saying, "Gangnam Style and Just Dance 4, I can't wait to see all the YouTube videos." Spoiler: It's going to be a lot of people doing the horse dance.
One of the words that doesn't show up in Ubisoft's announcement is "exclusive." We've reached out to Harmonix to find out if it's also working on some Gangnam Style for Dance Central 3.
Update: We checked with Ubisoft to see if the DLC included the moves from the famous music video or simply had new choreography.
"The chorus of the song has the precise moves from Gangnam Style," a Ubisoft spokesperson informed Joystiq. "The verses highlight some of the video's moves but also include [Just Dance 4] moves."
