I personally do not believe this was meant to be found. I am not going to even fathom to guess at the truth of the bar incident.
But...
to my knowledge has NEVER let such a slip occur. Their walled garden is built upon secrecy, NDA's, and black cloaks. For crying out loud, why would SJ allow his thunder to be stolen before the announcement? It makes completely no sense at all, and I cannot be sold otherwise.
So, either this is 100% a mistake made by an Apple employee (and if so, they know exactly whom, you can guarantee that.)
Or, it is the most devious thing they have done to mark the wrong trail; and that would be mind boggling.
