TB3 is supposed to be fully backwards compatible with TB2; it's just a different physical connector. That's why even Apple only charges $29 for the adapter.

Waiting a year is way too much caution for me. I wouldn't pre-order anything, but once other people post it works I'd feel safe to proceed.

These adapters support hooking TB2 devices to a TB3 host, but not the other way around.

Intel initially announced that TB3 devices would be compatible with TB2 hosts, but it looks like they quietly dropped this feature. It's _really_ hard to find a reference on this though.

This guy[0] seems to say it works with the Razer Core.

Looks like I had the wrong impression. Thanks for the link!

I thought the same thing as you, but it seems that at least some TB3 devices work with TB2 hosts, e.g. the LG 5K display: https://support.apple.com/en-us/HT207448
