4.12, from a VR perspective, was a very short turnaround for us, because of the timing of the Oculus SDK releases. So, there’s a few features coming, but the majority of it was spent laying the groundwork for things like the multi-slice and multi-view rendering mentioned above, platform compatibility for StereoLayers support, and the groundwork for VR loading movies, which will be available soon after 4.12. Unfortunately, we’re beholden to the engine release schedule, so we weren’t able to get it all out in time. 
As for the depth testing, I meant to include that with HDR support, since that’s a rendering / Android platform support question. VR is at their mercy for that one!
