Simply upgrading to that would quadruple Thunderbolt bandwidth to 160 Gb/s (20 GiB/s gross, so effectively maybe something like 15). That’s quite interesting for high-end SSD scenarios.
In that case, do we need to care when Intel supports it? Isn't it up to Apple Silicon to support it now, or do we need Intel to move first?
I could be wrong, but it was my understanding Apple just went to PCIe 4.0 recently, so 5.0 is a ways off.

If they could move to PCIe 5.0 and USB 4 [80] with the new Mac Pro and announced availability early in 2023, that would be amazing.

But I'm thinking it will be a Yikes/Sawtooth repeat where the first model is an M2 Extreme, and the next [M3] upgrade blows it out of the water.
