The futuristic prediction which seems to be not happening because people just don't want it is video which shows your face while you're talking on the phone.

That one's already happened. My new iPhone does video calls, and so does Skype on any computer with a webcam. That wasn't driven by demand, though, it was more that the technology all became ubiquitous for other purposes and it was easy to stitch it together to provide videophone functionality, even if it isn't actually used very much.
