The USB Implementers Forum (USB-IF) has released the specifications for USB 3.2. The new standard is supposed to allow for up to 20 Gbps (gigabits per second, not gigabytes per second) transfer speeds, thanks to two more sets of SuperSpeed pins. In order to get those speeds you need a USB Type-C connector.

While the USB 3.0 (aka USB 3.1 Gen 1) was capable of transferring up to 5 Gpbs, the USB 3.1 Gen2 interface was able achieve 10 Gbps. The new standard will double that once more hitting 20 Gbps. This is made possible thanks to a new physical “SuperSpeed USB” layer inside the USB Type-C connector. Using two 10 Gbit/s lanes up to 20 Gbps of throughput can be achieved. In order to hit this value, you will need a host and client connection that is compatible with the new standard.

Since the port hasn't changed, device manufacturers can still use the USB Type-C ports in their products and update to the USB 3.2 standard. It will take some time before first devices will become available to consumers and at the moment there isn’t any additional information.
