As there is no compatibility between OpenGL and the Vulkan API, many large GL code bases will not switch immediately. But older applications will still want to access new hardware features, so I believe that OpenGL is not dead yet, but will in fact live on for some more versions. I’m confident that we will see new hardware features exposed in OpenGL 5.0 (maybe at Siggraph this year?). Just as NVIDIA, AMD and Intel didn’t drop the Compatibility profile even in the latest OpenGL versions, I don’t expect them to drop support for new OpenGL versions any time soon. I guess it’s actually more likely that we will quite some OpenGL extensions which expose more Vulkan like features in OpenGL to help transitioning (e.g. the Vulkan shader “binaries” SPIR-V). Limited compatibility in the other direction at least for the shaders is planned by providing a GLSL to SPIR-V compiler.
