Just to add further... I think its great they haven't released some crappy video of an unfinished prototype in action just to satisfy peoples curiosity by delivering a poor initial impression. I think the fact that we haven't seen it says a lot about the professionalism by the management. No leaks.
The video montages that do exist on youtube show clean images that give a great teaser and create great anticipation of wanting to know more. They are creating some great interest globally. They have one opportunity to get it right. No doubt they will come out with an amazing marketing campaign that will hit the spot.
