first of all, people are taking this whole thing the wrong way, this has been standardised since 2009, it's the charger not the cable that this whole thing relates to, the regulations say that phone manufacturers should provide a cable for a USB charger, so that all you need to carry with you is your phones specific cable to usb, rather than the whole mains adapter, it does not standardise the connection to the phone. and i know most new tech i buy has already started to go down this route, Apple have done for years.
Apple will Continue to use the Dock Connector
a MicroUSB Connector is about 40% as wide as an Apple Dock Connector but only provides less than 16.67% of the functionality

now how do you suppose all of those are able to be done with MicroUSB, while also being able to securely hold a device in a dock, oh wait i know if we added 25 extra pins to it and made it it a bit wider, that would work...
