My theories of what new features & updates will be revealed
Siri will be able to predict your future. =P
iPhones will be able to call UFOs.
All iPhones will be bendable because of new flexible logic boards.
All iPhones will also be able to bounce like Flubber.
All iPads and iPhones will get full recharges by dipping them in water. [What? They get thirsty too!]
All iPhones will come with a free gorilla. (congrats to the winner of that new 6Gb Hard Drive!)
All iDevices will have built in 3D printing and come with the template to print your own 3D Apple Pony.
All iDevices will include a special build of OS9 that can transport you to a new reality.
And finally, all iPads will have the ability to unfold into a full sized iMac.
