It will be interesting to see what the final winner of GPU programming looks like. There's also the possibility of FPGAs making their way into consumer hardware, and right now the pure-Python library MyHDL is a great choice for those. There are a few attempts at abstracting over OpenCL like https://github.com/eholk/harlan https://github.com/eholk/harlan, and some intriguing domain specific attempts like http://halide-lang.org/ http://halide-lang.org/ but I think it will be a while yet before something takes over. I also don't think whatever it is can succeed without corporate backing.
