Didn't really wonder about it however it's hard to say since almost anything can be faked. Main reason i'm taking it at face value is due to the people behind what is going on and how it's truly an established field of research. Though that doesn't mean anything since someone could have gotten some store liquid nitrogen on the cheap then made some models to play with to tantalize viewers.
If it's real, surely a reliable source can be found where there is no techno music in the background (nothign against it, I like it, but it's not professional) and it isn't a video hosted on college humor.
Gizmodo.co.uk’s Sam Biddle said: ‘We can’t find any “JAPAN INSTITUTE OF SCIENCE AND TECHNOLOGY.” Its YouTube channel only has one video upload - and a Gmail address.
Plus, the fact that this is tied to a videogame screams viral ad.’

Well, as badly as I want to believe in the above piece of awesomeness, it is likely a hoax. The giveaways? Well, Sony Entertainment is credited as a copyright holder on the video, who just happen to be releasing a sequel to Wipe'out in February.
Also, the "Japan Institute of Science and Technology" and the logo shown on the video are an imitation of the real-world Japan Advanced Institute of Science and Technology. And finally, a careful look at the vapor trails of these two futuristic slot cars reveals some crafty CG work.
Still, as far as corporate-funded viral hoax videos go, this one is pretty great. Just don't hold your breath for a superconductive toy racetrack set popping up at Toys "R" Us anytime soon.
