Apple has confirmed the dates for its annual Worldwide Developers Conference (WWDC).

But before we start getting all excited about iPhone 5 or iPad 3, word is the event will shun Apple’s traditional formula and be focused purely on iOS software.

The five-day event begins on June 6th and takes place at San Francisco’s Moscone West.

Apple has said that it will unveil the future of iOS and Mac OS and perform demonstrations of the new kinds of apps that developers can build using advanced frameworks.

"At this year’s conference we are going to unveil the future of iOS and Mac OS,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. "If you are an iOS or Mac OS X software developer, this is the event that you do not want to miss.”

The event allows developers to bring their code to the labs and work with Apple engineers, applying development techniques and best-practices to enhance their apps.

In less than eight hours of the US$1599 tickets going on sale, the event has completely sold out. Not bad considering it took last year’s WWDC eight days to sell out.
