Leaked PS4 Launch Trailer & Viral Campaign

Yesterday a user on YouTube with the account name "SCELabs" (Sony Computer Entertainment Labs?) posted two viral marketing videos featuring 3D gaming and references to PS4. Most people think that it is of high enough quality and resembles Sony's style of marketing, yet don't think something as big as legitimate 3D gaming and/or the PS4 could have been developed under the radar for so long.
