Some food for thought, all reasoned speculation:
-The number of people at Apple currently allowed to physically handle a close-to-production version of the new iPhone likely numbers <100. Lots of people work on it, not many likely get to hold the whole enchilada in their hands at this stage >2 months prior to release.
-Of those, the number allowed to remove one from the Apple campus is probably <10.
-These are extremely senior people at Apple obviously, and so undoubtedly appreciate the significance of what they're carrying. IOW, the chances of one of them truly forgetting it somewhere is basically nil.
All of which leads me to believe it's either a fake, or a plant on Apple's part.
Given everything I see, I think it's a plant on Apple's part.
My $.02
