    With all this talk about the imminent new iPhone having 'only' 9 pins, it makes me wonder why there was a need for so many pins on the existing devices, and indeed why even 9 are necessary? After all, the USB port that it connects to has only 4 connections (2 power & 2 data)

    Look at hard drives. They had 40 pins, then 80 pins, then 7 pins (SATA, 4 data and 3 grounds). Eventually, engineers find a way to do more with less.

    They're dropping the video functionality in favor of AirPlay, Bluetooth, and USB.

    That has not been confirmed!

    Op micro USB doesn't offer anything close to the 30 pin or the new ? Pin connector.

    This micro ? Connector will carry power, data, audio and hdmi as a minimum!

    9 pins is what USB is...so it's probably just a USB 3.0 port, proprietary so it can have magsafe and to make it more suitable for docks.

    power, usb, HDMI, remote control, support. iphone 4 and 4s supports hdmi out via a special adapter (sold seperately.) which also requires an HDMI cable.

    the extra pin out were also for docking solutions. ipods used these for power and remote control.

    4 pins for USB which can probably double as power, USB 3.0 has more pins than 2.0 which means that iphone 5 may support usb 3.0. The rest could be for various docking solutions which probably require a 30 pin adapter (sold seperately) newer docks will use 9-pin.

    The question i have after this is? if they can get 19 pins in that opening. then why not do a 20pin MicroDisplayport / MicroThunderbolt?

    The hole in the leaked parts looks the right length for MDP but at 4mm that connector is just to tall. So 19-20 pins seems like a lot. still with 10pins they could do a half displayport with enough bandwidth for 720p display.

    Because dock accessories. Have you not noticed how the Android world lacks the same variety of dock accessories even though they all use USB ports? You can't get line level audio from a USB port for one thing...
