2 weeks to release and Apple still only has 3 guided tour videos. I wonder if they're still adding features which is causing a delay in the videos. The demo units (not the try on units) are still not full featured. I'm sure they're still working out bugs - but that wouldn't prevent them from making a video showing the features.
