Vulkan/Cuda Interop for users of Cuda/Open GL Interop

I currently use OpenGL combined with CUDA. I am primarily interested in using CUDA to perform complex calculations while displaying those results via OpenGL.

Will this change when Vulkan is introduced or will NVIDIA stick with OpenGL/CUDA as the preferred technique?

I also would prefer to stick with CUDA over OpenCL ( or whatever compute APIs will be included with Vulkan).
