Does anyone actually implement OpenCL 2.0 yet? Last I checked not even AMD supported it, and they're the only company that has a reason to care about advancing OpenCL.
Yeah, AMD has it now.

What quality?
CUDA has had support for Fortran, C++ and any language with compilers that could target PTX from the early days.
Also the graphical debugging tools are quite good. Debugging GPUs feel just like debugging any other application.
Meanwhile on OpenCL land, plain C and printf debugging.
Only with OpenCL 2.0 Khronos finally started to address these issues, so what quality?!
