They demonstrated USB 3.2 but used the USB 3.1 Type-C data cable at that time. Type-C is also the only recommended interface for USB 3.2 and it can also continue to be compatible with the current data cable. For example, users can connect the USB 2.0 Type-C cable to USB 3.1 Type-C hole, but the speed will reach the level of USB 2.0; UBS 3.2 supports dual-channel transmission,which is equal to double the bandwidth. And it can double the transmission rate of USB 3.1 Gen 1 to 10 Gbit / s, Gen 2 to  20 Gbit / s--but the premise is that the machines on both ends must support USB 3.2.

This version is expected to be officially released at the USB Developer Days North America in September this year.

(VCOM)USB 3.2 Uses Same Cables, Doubles Data Rates

(VCOM)USB 3.1 Gen 1 was formerly known as USB 3.0; USB 3.1 Gen 2 was formerly known as USB 3.1

Although the speed of USB 3.2 has doubled, it is still a long time for popularization. The threshold is still high because new chip support is required. AMD and Intel have natively supported the USB 3.1 Gen2 interface in the past two years. And USB 3.2 will be the third-party chip at first. It is expected that the products will be available in the second half of 2019.
