The conference kicks off on 11 June and lasts until the 15th. Last year Apple used the opportunity to tell us all about iOS 5, which introduced wireless updates and a notification system shamelessly nicked from Android.
You don't have to be a master mathematician to figure out that one year on, we'll probably see iOS 6 given an airing. What are you hoping to see? Let me know in the comments.
New Mac OS X details are also likely to emerge, with Mountain Lion -- the latest version of the Mac desktop software -- due out in the summer.
Traditionally Apple has used WWDC as an opportunity to give a new iPhone an airing. It broke that streak last year however, choosing instead to show off its new blower in October at a separate event.
Apple could go back to a summer reveal, but I think it's unlikely, as it would mean the iPhone 4S being on sale for less than a year. With the Cupertino company announcing it flogged 35 million 4S' in the last three months alone, I can't see it replacing a winning product earlier than necessary.
WWDC will run from 11-15 June in San Francisco. If you were hoping to attend, bad luck -- tickets have already sold out.
What do you want to see in iOS 6? Let me know your thoughts in the comments, or on our Facebook wall.
