Apple today announced that it will open its annual Worldwide Developers Conference (WWDC) with a keynote hosted by senior vice president of Worldwide Product Marketing, Philip Schiller. The news about the keynote, which is set for June 8th at 10:00 AM PST, isn't about who is running things so much as who won't be--CEO Steve Jobs.

Jobs, who has been on medical leave, was originally set to make a return to the company next month--which many suspected would coincide with the WWDC keynote, over which he has traditionally presided. The absence of Jobs, a long-time media darling, from the last few Apple product announcements has made nearly as many headlines as the products the company has rolled out.

Most are expecting Apple to use the WWDC keynote to introduce the third iteration of the company's popular iPhone handset. But barring a famous "one more thing" involving Jobs himself, the absence of the company's head will likely cast a shadow over the new product.
