I just stumbled across this article on anandtech, which states, that thunderbolt 3 won't carry DP 1.3. So does this mean, that the next iteration of the iMac 5k is unlikely to regain the target display mode or could Apple add a dedicated DP 1.3 port to the iMac, which won't be a thunderbolt port?

Either way, it's an interesting read.
