Of all of iPhone 6 render images floating around the web, none of them seem to fully capture ALL of the key graphic design elements of an official Apple graphic.
As mentioned by gadgetlove.com in their Interactive 360 Degree iPhone 6 article, the key components seemingly missing from other renders include:
1) Myriad Pro Light font, with -40 tracking of course :)
2) a pure white background
3) a minor reflection from the phone
4) a slightly matted finish
5) And, of course, a new borderline-hyperbolic slogan.
What else an apple.com design staple?
Here is a GIF preview if the interactive version from GadgetLove.
