It looks like Lynskey is going to have a more race oriented gravel bike coming out called Pro GR. From what I can tell from the pic, it looks like the same tubing as the Pro Cross but I assume with gravel geometry.
I'm on my second year of gravel racing/riding on a Lynskey ProCross and it has been great. Many of the races include some more technical sections (including one that ended with a cyclocross circuit) so the ProCross' geometry has been perfect for me, aggressive enough but stable during 40mph descents This GR PRO looks sweet though.
