Perhaps you should change the background image in the demo video away from a photo of a galaxy. I'm sure there's many images (e.g. http://archive.org/download/313253main_moon_landscape_HI_ful...) that don't so directly evoke the OS X default wallpaper.
100% agree. I personally only noticed this tonight shortly before the launch (at which point it was too late to change), but I definitely dislike the fact that we (in fact, the video was created by a fan) used a video which showed off a wallpaper Apple used in OS X.
Frankly, I expect we'll try to get that amended soon.
