Apple has confirmed today that June 6 will see Chief Executive Officer Steve Jobs take the stage at Moscone West, San Francisco, California, to deliver the Worldwide Developers Conference 2011 keynote alongside a number of fellow executives.

“Apple CEO Steve Jobs and a team of Apple executives will kick off the company’s annual Worldwide Developers Conference (WWDC) with a keynote address on Monday, June 6 at 10:00 a.m,” Apple confirmed today in a press release.

The Cupertino, California based company revealed that the keynote address will be featuring:

· the unveiling of Apple’s next generation Mac OS - Lion, the eighth major release of Mac OS X; · iOS 5, the next major iteration of Apple’s mobile operating system for iPhone, iPad, and iPod touch; and… · iCloud, an upcoming cloud services offering from Apple.

With Steve Jobs’ surprise appearance at the March iPad 2 event, much of the negative speculation surrounding the man’s health had toned down, but analysts are still concerned that Jobs is close to retirement.

His confirmed appearance at WWDC 2011 should do well to extinguish this fire, more so if the CEO appears vivid during the show.

Jobs is a cancer survivor who underwent a liver transplant and several other medical procedures that left him frail, and extremely weak in appearance.

Due to announcing his second medical leave in just as many years, publications like the Enquirer made sure that a burning debate about his return as CEO was kept alive.

The tabloid showed images of the rail thin CEO earlier this year while quoting so-called experts as saying Jobs had mere weeks to live, based simply on his appearance.

Jobs later made a live appearance to launch the iPad 2 looking healthy, albeit still very thin.

We’re holding our breath for another iconic keynote presentation from Apple’s chief, as well as for clues that his ongoing medical treatment is successful.
