Microsoft has been showing off quite a bit of the Xbox One recently, their Xbox One demo video was actually quite impressive.
Sony have yet to show off a real demo on the use of the PS4, even though it's only four days away from release in the US.
However today Sony has released a weird PS4 unboxing video, a very dramatic one. The style of it very much copied from Daft Punk's Random Access Memories unboxing video, but then Sony does own the rights to Daft Punk. Not sure what Sony was thinking, most probably just a marketing ploy to get people talking about it.
For reference, I've also posted the Daft Punk video below.
