AMD has announced FreeSync 2
http://www.amd.com/en-us/press-releases/Pages/freesync-2-2017jan04.aspx
In short, it's a new "display pipeline" for HDR-displays.
By default, HDR content is tone mapped twice, once by the app, and then by the monitor to fit it's spec (none of the HDR10 displays fill the entire spec anyway, most are nowhere near).
FreeSync 2 supporting pipeline (needs support from app, gfx card and monitor) eliminates the monitor tone mapping -step by doing it right the first time to fit that particular monitors spec, and thus lowering latency.
All FreeSync supporting Radeons support FreeSync 2 too, and all FreeSync 2 displays will support FreeSync, too.
