The new iPod Shuffle has been redesigned to have just one port; a combination of a headphone and USB. We know how every generation of the iPods is thinner and smaller so imagine how much space Apple could trim by removing the Dock Connector. Sure, it would throw a spanner in the accessories market but that is typical Apple practice; just look at the new Nano and its incompatibility with the old Nano accessories.
I predict that the next Nano update and the rumored iPod phone will have the headphone/USB port and the full size iPod will be the last model to use the Dock Connector.
