Thunderbolt 3 Uses the USB-C Connector ⇥ arstechnica.co.uk

This is awfully compelling. USB-C kind of replicates a lot of Thunderbolt’s functionality, but in a worse way. This allows for the full PCI-e spectrum of things to connect via the same cable that provides power and two 4K video streams. In Apple terms, a next-generation Thunderbolt Display paired with a next-generation MacBook could connect via a single cable and output to a 5K Retina display while being charged from that one cable. That sounds pretty much perfect.
