SolidSnakex who is a well-known personality NeoGAF forums has taken footage of the same track loading in real-time (not Kotaku time); which, by the way, takes just about 28 seconds. The link to the video is below.
Unrelated but on topic, seems Kotaku will post ANYTHING to get their annual bribe from MicroSoft. Or to get hits for that matter. Flamebait article, and it still remains on the site. Asscraft simply states : "Our users have reported this may be fake. Make of it what you will" in other words: FLAME ON.
