Built in stereo eye tracker so the phone knows where you are looking, with the possibility of using blinks or sustained gaze fixation to select buttons.
Larger screen that creates 3-D effect through parallax motion using the eye monitoring from above.
Solar or kinetic charging integral to the phone - no more issues about batteries except when they wear out.
Self-healing (up to a point) nano-material exterior
Intrinsic language parsing (Siri, but without the need for network access)
Graphic development environment that allows mere mortals to create apps for the Mac, iPhone/iPod, and iPad without having to learn arcane, counter-intuitive programming languages
The ability to control not only TV's, multimedia centres, but iAppliance interfaces that Apple is beginning to create to dominate the home & automobile automation market (presumably based on Apple protocols and/or chips that manufacturers can use to control heating systems, cars, ovens, phones security systems, etc...)
Bulletproof anti-theft hardware and software
min 128 GB memory
No *&*^%$^&& mechanical home button. Instead, there will be a touch-sensitive Apple logo with no moving parts.
Of course, I could be wrong.
