Apple Announces WWDC 2010 Dates: June 7-11
Apple today announced that this year's Worldwide Developer Conference (WWDC) will take place from June 7th through 11th at San Francisco's Moscone West convention center.
The Apple Worldwide Developers Conference (WWDC) is the premier technical conference for developers innovating with Apple technologies. Over 1,000 Apple engineers will be at Moscone West to present advanced coding and development techniques that will show you how to enhance the capabilities of your applications with the revolutionary technologies in iPhone OS and Mac OS X.As always, the conference will include technical sessions and hands-on labs for attendees, as well as other special events. Registration for the conference is priced at $1599, with tickets for the conference having sold out increasingly quickly over the past couple of years. Given the short lead time on ticket sales this year, developers will likely have to move quickly to secure a spot in the conference.
Apple is widely expected to introduce its new iPhone hardware during a keynote address at the event, although the device has already received considerable publicity since Gizmodo published details on one lost by an Apple employee in a California bar.
Update: A number of observers have noticed a heavy emphasis on iPhone OS in this year's conference, from the headline banner featuring App Store application icons to the elimination of Mac OS X as a category in the Apple Design Awards. As Daring Fireball's John Gruber notes, the iPhone OS emphasis strongly suggests that Mac OS X 10.7 will not be previewed at the conference.
