I think this was a controlled leak to get the stock up! Lets keep in mind Apple is a public company. As this Freudian slip(COUGH COUGH) gets around the net Apple's stock will rise a bit.
That would only be beneficial if it was a "pump and dump" situation. Apple isn't that shady, plus it would really interest the SEC. If what you are saying is true, and Apple has nothing the stock gets hammered and hard. OTOH if the Apple does for tablets what it did for phones the stock price is going to skyrocket on the 27th anyway.
That said, I agree this is a controlled leak, but to get people pumped up for the announcement, not to artificially bolster Apple's already hefty stock price.
