Vulkan: long may it live, and prosper. Seriously, following the links, it sounds awesome. Multi-platform -- Linux, Android and even Windows. Widespread industry support, including Nvidia, AMD and Intel. Sounds like it will interface smoothly with OpenGL (as in, write your most speed-critical code in Vulkan and the rest in OpenGL?), OpenCL and other open standards administered by the Kronos consortium.
