If the iPad 3 dock connector parts pictured below are real, then the next generation tablet will feature a slimmer, smaller connector. Although the parts have the same 30-pin configuration, the form factor is streamlined and would result in incompatibilities with current dock connector accessories. The parts were revealed by a Asian supplier website and represent an iPad 3 prototype design.
There's no telling if this iPad 3 prototype is the production model, however Macotakara claims the device is ready to be manufactured in January and could be released as early as March 2012. A change in the dock connector size would make the iPad 3 the first mobile device since the 2003 iPod not to use Apple's standard size cables.
