I think esync will especially benefit people looking to use low latency.
Regarding plugins that don't display, most of them are probably due to incomplete d2d support. What is good is that Valve is working on DX10/11/12 support on vulkan, that ought to free up development time for code weavers to work on other stuff. It also seems to me that valve is gonna need working APIs for a lot of stuff that still isn't properly implemented. That can only be a good thing for us too
