Hate to "me too" here, but just doing the same set of searches. There are a couple of cables - but in the $35 range, why would I do that? I have six locations where I have workstations and monitors.
Apple didn't do a good job on this rollout - for all the time they had. I have four thunderbolt monitors in three locations... did they just expect that I was going to add $5K to replace the monitors and another $500 in connectors to the $5K bill for the new MBP? or buy another six power bricks for $500?
And they left out the memory upgrade. For anyone doing MPP development requiring more than two or three VMs or docker images - this machine doesn't help them. "power saving" was the reason given - why that trade off of battery life over memory isn't a customer choice - well. enough said.
My current MBP is 4+ years old, so I don't have much choice.
