It also has a SuperPort connection, which is a rebranded TB3. So its seems like waiting for TB3 devices/boxes is the only way for now,

I bought a MSI GT 72 - 6QD Notebook. It has the new M.2 PCI-E 3.0 x4 slot with 32GB/s. (the picture is from a desktop mainboard) Any adapters out there to use it? Anyone already tried it?

So its a normal Thunderbolt 3 Controller. Dell uses Intel Thunderbolt Driver 15.2.35.250. Its good to know no additional/updated cables are required. My MSI GT72 6QD uses Thunderbolt Driver version 15.2.34.5. Will try to install the Dell one later, to see if the chipset is supported. /edit: Windows Update already updated my driver to 15.2.35.250. So yeah, normal TB3.

You are right. Plug and Play will certainly require a fitting UEFI. Lets hope the rest wont be that much of a hassle, at least not more than the current solutions.

It will work with a normal TB3 Cable. The rest is typical proprietary business bs. It already worked with TB2, why should it stop with TB3? PCI-Lanes are in the cable, so nothing prevents it. They just want to get a standard up and running and licence fees for a "egpu-ready" label on the notebook. "Unpredictable.." means, they wont have to give support for notebooks without an "egpu-ready" label.

Ofc Thunderbolt 3 is not enough. Becuase you only get 100 Watts through TB3. Thats not enough to power a egpu with the pci-e slot. All the demos intel showed so far have used an additional psu. (edit: there was one demo with an mobile gpu which didnt need an external psu) I think that is what the reply meant. Wouldnt make sense if it needed another cable additional to tb3. This wont be the case. This video is from the end of September and only uses TB3 + external PSU:
