Intel Announces Thunderbolt 3

Normally introductions of new ports and protocols are met with "oh great, another one!" reactions, but this new one is almost perfect:

I was on board with the idea, but one glaring omission made me smack my head on the desk:

"Speaking of encapsulation, Thunderbolt 3 also includes an update to the DisplayPort side of matters, though likely not what everyone has been expecting. With the increase in bandwidth, Thunderbolt 3 is able to carry twice as much video data as before. However Intel is not implementing the latest version of DisplayPort – DisplayPort 1.3 – in to the Thunderbolt 3 standard. Instead they are doubling up on DisplayPort 1.2, expanding the number of equivalent DisplayPort lanes carried from 4 to 8, essentially allowing one Thunderbolt 3 cable to carry 2 full DisplayPort 1.2 connections. The end result is that Thunderbolt 3 will not be able to drive the kind of next-generation displays DisplayPort 1.3 is geared towards – things like 8K displays and 5K single-tile displays – but it will be able to drive anything 1 or 2 DisplayPort 1.2 connections can drive today, including multiple 4K@60Hz monitors or 5K multi-tile displays."

Can't have it all
