Apple has officially confirmed that CEO Steve Jobs will continue the tradition of presenting the opening keynote address at its Worldwide Developers Conference (WWDC) 2011 on Monday, June 6 at 10:00 AM. Along with a team of Apple executives, he will unveil Apple's next generation software.

First up is Lion, the eighth major release of Mac OS X. Second is iOS 5, the next version of Apple's mobile operating system which powers the iPad, iPhone, and iPod touch. Last but not least is iCloud, Apple's upcoming cloud services offering. Just like that, almost all the rumors have been either confirmed or crushed, including the likelihood that the iPhone 5 has been delayed.

Apple announced two months ago that it would hold its annual WWDC from June 6, 2011 to June 10, 2011 at San Francisco's Moscone West. The company said it will "unveil the future of iOS and Mac OS" but now we have the exact names, as well as the third piece of the puzzle.

WWDC is primarily a developer conference, meaning Apple uses it to demonstrate software and technologies for third parties interested in its platforms. The event will include demonstrations of the new kinds of apps that developers can build using Apple's frameworks as well as more than 100 technical sessions presented by Apple engineers.

Mac developers will be given a closer look at how to develop world-class Mac OS X Lion applications using its latest technologies and capabilities (Apple will likely push its Mac App Store and argue the advantages of using it). Mobile developers will be given a tour of the latest capabilities of iOS 5 and learn how to improve the functionality, performance, and design of their apps.

All developers will be able to bring their code to the labs and ask over 1,000 Apple engineers for help with enhancing their apps. They will provide developers with code-level assistance, insight into optimal development techniques, and guidance on how they can make the most of iOS and Mac OS technologies in their apps. Further details on iCloud were not revealed, and we only just heard of the name last month.
