Apple's annual Worldwide Developer Conference (WWDC) will take place from June 11-15 in San Francisco, the company announced today.

"It's the week we've all been waiting for," Apple said on its website.

Tickets to WWDC, which will be held at Moscone West, run $1,599 and are limited to one per person and five per organization. Tickets to last year's WWDC sold out in one day (Update: This year's event sold out in less than two hours).

"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," said Philip Schiller, Apple's senior vice president of Worldwide Marketing. "The iOS platform has created an entirely new industry with fantastic opportunities for developers across the country and around the world."

Last year, Steve Jobs took to the stage to unveil iCloud and iOS 5, though both features were not officially released until later that year.

This year, Apple will likely talk about the next version of OS X, Mountain Lion, a preview of which was unveiled in February, and possibly tip some details about iOS 6. For more on that, see 6 Features We'd Like To See In Apple iOS 6.

In years past, Apple has also used WWDC to unveil its new iPhones, but it broke from tradition last year and waited to unveil the iPhone 4S until October. During yesterday's earnings call, Apple said it sold another 35 million iPhones during the last quarter, so it can likely afford to wait until the fall for another iPhone release.
