I would have to say Fake because:
- Why would they use a black background rather than the colour dynamic wallpaper they have been using in all the iOS 7 promo material?
- Why use a head-on shot when lately (iphone 4 and up) they have used angle shots to show the hardware?
Likely because they have new features to showcase with the phone using a front-on shot. They have iOS 7's new homescreen to showcase, and they have a new home button design with biometrics to showcase. The angled shots wouldn't do a good job of showing off these new things. The angled shots did a good job of showing off a new design and thinness, which is not necessary this time. More important to get a front-on shot and show off the new iOS 7 design and the new home button design.
I love peoples logic when it comes to these kinds of things. Since Apple previously did things one way, that means they could NEVER do things any other way
