I really hope they find a way to include a compatible Thunderbolt 3 experience. Using a Thunderbolt 3 Dock has become a must for me at this point, i'd hate to go back to multiple cables/less than 2*4k/60
There exist desktop AMD motherboards with Thunderbolt 3. Laptops will probably be trickier due to power use.
I share that sentiment and I can't wait for USB 4 to show up in consumer products.
I wonder if USB4 Devices will be actually really compatible with current Thunderbolt 3 Devices, or if it's a "technically yes but not really" situation.
