Hopefully nobody will make anything with A or B and every device will have C in it. That would be fantastic.

My only concern is that it would look too much like the current micro USB, and we'll see people jamming these new cables into the bottom of their phones, breaking their connectors.

In 2012, the USB Power Delivery (PD) specification was released. The USB PD specification provides the ability for 5 V devices to draw more than (the USB Battery Charging specification limit of) 7.5 W of power from USB "PD-aware" ports when using PD-aware USB cables.

The specification also allows USB PD ports to provide even greater power at higher voltages over PD-aware cables - up to 36 W at 12 V and 60 W at 20 V (for micro-USB connectors) and up to 60 W at 12 V and 100 W at 20 V (for standard USB A/B connectors).

According to the USB 3.0 Promoter Group, a proposed USB Type-C connector and cable "will support scalable power charging," presumably by supporting the USB PD specification.

The planned USB Type-C plug and receptacle will not directly mate with existing USB Type A and Type B plugs and receptacles but new-to-existing cables and adapters will be defined. A final USB Type C specification is expected to be published "by the middle of 2014."
