In less than a day, WWDC 2011 has completely sold out.

Apple's annual Worldwide Developers Conference was announced earlier today, and is to take place from June 6th till June 10th at Moscone West.

Tickets went on sale for developers to go and see the future of iOS and OSX. In around 12 hours, all the tickets had completely sold out, which, compared with WWDC 2010 which took 8 days to sell out, is the fastest sell out time ever.

What are we going to see at this years WWDC? Any Developers lucky enough to get a ticket?
