Has anyone seen a Thunderbolt 2 to 3 cable in the wild? I've just ordered a 2016 MBP, and have a few Thunderbolt 2 devices. I've ordered a couple of adaptors, but with my USB cables I'm replacing the cable instead of using adaptors. Would like to do the same thing with Thunderbolt but doesn't seem to be any available. Is there some kind of translation going on in the adaptors or something?
