Its vapourware. The press hasn't said anything because there is nothing to report. Until a game integrates the technology we aren't going to see it used. As far as I know the Nvidia Fun house for VR uses it but its an Nvidia technology demo for Pascal and it doesn't show off the multimonitor capabilities just the VR side.
We haven't even got a UI for placing the monitors yet so its a way off. Honestly I don't think its going to take off until both companies support it and it gets added to DirectX.
