Precision 7740 & Ubuntu 20.04

Hi, 

I made a clean install of Ubuntu 20.04 (before had preinstalled Ubuntu 18.04).

Is there a motion or some dates when Dell is going to support Ubuntu 20.04 for the Precision line (not only 775x series).

Installation overall went smoothly, but there are some issues with Wifi and Bluetooth. 

Would be great to know where we with older models stand in the line of support, while one of the main reason to go with Precision would be OEM support, and to avoid DIY!.

If there's a lack of it, then there is no point in buying Precision which supports only one LTS version of Ubuntu.
Then I can go for anything and DIY!

Is there any plan to release 20.04 image for Precision 77x series? Is there some unofficial repos already 

Tnx
