Apple

And just like that, it's a sold-out show.

At 5:30 a.m. PT today, Apple announced the dates -- June 11 to 15 -- for the 2012 edition of its Worldwide Developers Conference, which will take place in San Francisco. By 7:30 a.m. PT, the company had updated the WWDC Web site to say, simply, "Sorry, tickets are sold out."

The focus of the event, of course, will be on Apple's mobile and desktop operating systems -- the lines between which have begun to blur as Apple seeks to give users the same experience regardless of device. With the newest version of OS X, called Mountain Lion, Apple is bringing many iOS features to the Mac.

"We have a great WWDC planned this year and can't wait to share the latest news about iOS and OS X Mountain Lion with developers," Philip Schiller, Apple's senior vice president of worldwide marketing, said in a statement. "The iOS platform has created an entirely new industry with fantastic opportunities for developers across the country and around the world."

The event will feature more than 100 technical sessions presented by Apple engineers.

At last year's WWDC, Apple unveiled iCloud, iOS 5, and some features of the earlier Lion version of Mac OS.
