And how many times has Apple done this? Answer none. Trent Reznor, by your own admission, has.
Tech companies simply do not "loose" prototypes as a marketing scheme by in large least of all Apple - When Apple leaks something, they have specific things that they do - this is as far away from that as possible.
Trent Reznor (a musical AND marketing genius) has done it. Very successful AND free.
No reason why Apple would not. Welcome to the future. Open your mind.
