It's that time of year... September is traditionally the time of year for some shiny new apple goodness to be announced. In this case we do know a few things for a fact: we know that iOS 8 and OS X Yosemite will be out this fall so there will likely be announcements about that. We can be relatively certain that there will be an announcement on the iPhone 6 (possibly two different models) and more details to do with the iPad Air 2.
What else can we hope to hear about? There's rumour that we may hear about the fabled iWatch. Maybe we'll get lucky an there'll be information about the iTV?
There is usually some correlation or clue hidden in the tagline of the invitation; in this case the event is on September 9th and the tagline is "wish we could say more".
