EVGA uploaded a video that promises "a new Darkness is coming". The teaser briefly features the AMD Ryzen logo (without text) so the obvious conclusion here is that EVGA is working on an AMD X570 DARK motherboard. Presumably, this motherboard will get the new X570S chipset, which doesn't require active cooling.
At the moment, we don't know when EVGA plans to launch its first AMD-based motherboard but it will likely be sooner rather than later.
