Cook appeared on CNBC where he said the next-generation of iPhones would be quite impressive:
Cook went on to reiterate how excited he and everyone at Apple is about the innovation that's in the pipeline. Of course, none of these quotes actually mean anything. Take a look at any smartphone in anyone's pocket right now -- Android, iOS or even Windows Phone -- and there's a fair chance people would wonder how they ever lived without it. Smartphones are amazing and essential pieces of technology. There's a reason why you can always find polls that show more people would give up sex before giving up their smartphone.
So, it's hard to imagine what Cook might mean with that sort of promise. The rumors have said the next iPhone would have a dual-camera system and stereo speakers, but those hardly seem like things people can't live without (especially since they can be found on other phones right now). There have also been rumors of wireless charging from distance, which would get closer to fulfilling that promise.
Only about four months before we find out though.
