The Freesync 2 implementation is great for games with unlocked framerates. It's an uncanny valley because you don't want devs to ignore the majority who will not have Freesync 2 monitors. Features are good regardless.
Also pics of the Scorpio Dev kit.

Also the reports of a front panel screen giving devs information of framerate is also true.

There is a lot of added features to the HDMI spec over the last couple of years 4K, HDR, VRR and Freesync...I am looking to buy a AV Receiver to have in between the Scorpio and my monitor but I have to make sure it's compatible with the 2.1 HDMI spec.
Should have more information after the Summer on updating monitor and receiver.
