On the other hand: Even if the overhead for OpenGL can be lowered a lot (and I believe this is possible), this will be released as extension set - not as an elegant revised API as new DirectX versions do (see the Longs Peak fiasco).

The zero overhead talk was done by guys from Intel, AMD and NVidia - I think it's rather probable that this will end up in core OpenGL later. Especially if MS is reacting to Mantle as well. It's not "will be released", it's in current drivers - some in extensions, some in core Opengl 4.4 or earlier. As far as OpenGL backwards compatible approach, I think that's pretty much a necessity as long when you consider the stakeholders. D3D and OpenGL are pretty similar from 10000 ft. Really the GPU vendors should just open up instruction sets, binary formats and ABIs for their devices, and focus on writing high quality open source compiler backends for them, and let people program GPUs whichever way they want.
