It's amazing how Nikon seems to put so little effort into promoting their product. Canon, on the other hand, seems to have this whole promo thing down pretty pat with excellent shorts (both story and cinematic) and breakdowns of their videos.
What's up with that Nikon?? Take a page from the Canon playbook and show us what the D800 can do! I'm a Canon shooter and even I'm worrying for you!
But the videos of Canon are not FullHD, not even 720p...so they cannot be videos to compare or to see real noise and other things of video. If Canon gives FullHD videos then it will make a better promotion.
In this youtube channel you will find some really good videos for low light high ISO situations (3200, 6400) comparing D800, D4, 1DX and they are all real videos not fake.http://www.youtube.com/user/FenchelJanisch2/videos
