As usual before yet another big Apple event, the psychic friends network is in overdrive in anticipation of the iconic computer company’s “Let’s Rock” media gathering in San Francisco tomorrow.

At this point, I think Apple could announce a change in the color of its bathrooms at its Cupertino HQ and it would be mayhem among the Mac faithful.

Nonetheless, even though what will be announced is likely to be a series of incremental improvements for Apple’s line of music-playing products–iTunes, iTouch and, of course, the iPod–and even the possibility of a revamped design, it’s astonishing how striking the hype is around the event.

Of course, that kind of passion from core users is a blessing for any tech company, and it is hard to quibble with Apple’s stellar ability to market every jog and tittle of its product development as if it was the second coming.

But the most intense focus will more likely be on Apple’s leader, CEO Steve Jobs, whose gaunt appearance at the Worldwide Developers Conference in June set off a flurry of discussion about the exact state of his health.

That talk has since been less frantic, despite the fact that there actually has been no clear announcement from Apple (AAPL) on the delicate subject (and Jobs’s colorful off-the-record chat with the New York Times’s Joe Nocera does not count, folks).

In any case, because AllThingsD.com cannot resist either, Digital Daily’s John Paczkowski will be there liveblogging “Let’s Rock” from the Yerba Buena Center for the Arts, with all the news that’s fit to post.

And, of course, everything else too.
