Sad to know that the 2015 one-port Macbook only has USB-C.

Here's the fine print:
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.

And a really nice footnote, of interest to us all:
... gamers will be happy to hear that Intel is finally moving forward on external graphics via Thunderbolt, and after more than a few false starts, external GPUs now have the company’s blessing and support. While Thunderbolt has in theory always been able of supporting external graphics (it’s just a PCIe bus), the biggest hold-up has always been handling what to do about GPU hot-plugging and the so-called “surprise removal” scenario. Intel tells us that they have since solved that problem, and are now able to move forward with external graphics. The company is initially partnering with AMD on this endeavor – though nothing excludes NVIDIA in the long-run – with concepts being floated for both a full power external Thunderbolt card chassis, and a smaller “graphics dock” which contains a smaller, cooler (but still more powerful than an iGPU) mobile discrete GPU.
