USB4 is set to feature Thunderbolt 3 compatibility as well. Until now, Thunderbolt 3 was only available on the most premium laptops and computers, as device makers had to work with Intel directly to source the technology. Intel started certifying devices with support for Thunderbolt 3 in 2015, and in 2017 it chose to open the standard.
Thunderbolt 3 integration also enables the simultaneous transfer of both data and display protocols, meaning that you can daisy-chain 4K monitors and other Thunderbolt 3 devices, like external storage or GPU enclosures, together into one cable that connects to your PC.
50 companies including Intel, which co-engineered Thunderbolt with Apple, contributed to the new standard.
"The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution", said Brad Saunders, USB Promoter Group Chairman.
The advent of USB as a ubiquitous connection standard is one of the best things to happen to the PC.

USB4 doubles throughput up to 40 Gbps across a two-lane interface with certified USB Type-C cables. We have no idea what the first implementation of the news USB4 standards will be called and won't until it's released in mid-2019. That broadening of access to the technology could see a proliferation of today's more fringe technologies, like high-resolution displays and higher-fidelity virtual reality - not to mention even faster power delivery. So, consumers need to understand that although technically "USB 3.2" runs over USB Type-A or USB Type-C, you'll only get the full performance of USB 3.2 Gen 2x2 over a USB Type-C cable.
Hot on the heels of releasing the USB 3.2 specification - and the abject confusion it's likely to cause consumers - the USB Implementers Forum (USB-IF) announced that the 40 Gigabits per second (Gbps) data transfer rates and multiple 4K display support that are exclusive to Intel's latest proprietary Thunderbolt 3 port will be made available to generic USB-C ports. That also means it's arbitrary and certification has no real value; non-certified devices and cables can perform as good or better than certified devices and cables. By contrast, USB 3.2 tops out at 2.5 GB/s.
It is expected that the USB-IF will come out with more tech specs regarding USB4 at around Computex time.
Effectively, this means that 40Gbps will soon be the new universal standard for all future USB ports.
Ultimately, relinquishing control over Thunderbolt 3 is indeed a "significant milestone for making today's simplest and most versatile port available to everyone", as Intel General Manager for Client Connectivity Jason Ziller said in a statement. The group is also hosting the USB Developer Days 2019 event later this year. With the announcement of the USB4 (no space!) specification, the group has reached the apex of powerful features/confusing nomenclature.
