Card is already done.
Waiting on drivers.
(may need to adjust after(if?) drivers release)
what drivers you waiting for? The driver for windows 7 and 10 on 1070/1080/1080ti is already out that we can use in bootcamped mac. I dont think we will ever see OSX driver for 1070/1080/1080ti. Its dead end for OSX support from Nvidia on newest video cards it seems.
With macvidcard flasing service for 1070/1080/1080ti, it will extend the life of mac pro for us who want to use in bootcamped mac (windows 10) to take advantage of PCIE speed at 2.0 and superior performance out of classic mac pros for seveal more years.
I do video editing and gaming on my bootcamped mac now (windows 10), hardly ever use osx anymore.
Please consider to offer flashing service on 1080/1080ti for those who only
use bootcamped macs (windows 7 or 10) to take advantage of pcie speed at 2.0 and to add notes that customers understand that there is no support for osx drivers on 1080/1080ti.
