Intel has made good on their promise from 2017 to release the Thunderbolt specifications to the industry so that upcoming products can offer that connection without being tied to an Intel license and the possible limitations included therein. Today Thunderbolt 3 was released to the USB Promoter Group, who promptly undid the insanity that the USB-IF released upon us last week by promptly announcing it will be the basis of USB 4.
Thanks to their lack of an obsession over stringing letters and numbers to the back of USB 3 we will end up with a certified standard that provides "two-lane operation using existing USB Type-C cables and up to 40 Gbps operation over 40 Gbps-certified cables" (pdf link). It will maintain backwards compatibility with previous Thunderbolt generations as well as the various flavours of USB 2 and 3. It may or may not be compatible with the new ones, such as USB 3.2 Gen 2x2 ... indeed one might hope they refuse to accept such things into their specifications.
Considering that the USB-IF and USB-PG are closely related, this new nomenclature will be the new standard and last weeks announcement just a memory.
"Releasing the Thunderbolt protocol specification is a significant milestone for making today’s simplest and most versatile port available to everyone. This, in combination with the integration of Thunderbolt 3 into upcoming Intel processors is a win-win for the industry and consumers."
