Improved camera specs or iOS6?

When comparing the camera specs of the 4S and 5 on Apple's site, both reputedly are capable of panorama. The number of elements, backside illumination, megapixels, f-stops, etc. are identical, except the 5's camera is thinner.

Okay. So if the 5's camera is capable of still shots during a video, that's now a function of the software, since the hardware is the same, correct? And since the 4S will run iOS6 without modification per Apple, then it too should be able to take stills during video?

Any devs with beta experience to chime in?
