Do OpenCL + OpenGL as standards = standards-based games?
Only time will tell, of course, but what a boon that could be to OS X and Linux. I know the whole ball of hype around OpenCL has been for scientific clusters and business-critical apps. However, if there's a standard way to get vector math for game logic and physics that meshes well with OpenGL for graphics, and assuming SDL or something is up to the input tasks and audio, then that sounds like a good cross-platform substitute for DirectX.
With Apple, IBM, ATI, Arm, NVidia, and more behind it, it might actually catch on well enough to gain some traction among developers. If the cross-platform (OS and hardware) wrinkles can be ironed out and the end-user libs work acceptably well everywhere, not only things like render farms and investment banking could use it. Everything that needs lots of processing help from a vector engine could use it. That includes games -- and for more than graphics -- as NVidia's few PhysX titles have shown us.
