One thing to note is that new versions of OpenGL typically do not add new features - they consolidate and standardize features that vendors have already added as extensions. Unlike DirectX, vendors can add support for new hardware features to OpenGL without waiting for another company to update the API.
What part of "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn" don't you understand?
I am glad to see OpenGL moving along, I really think it is valuable for there to be an open standard like it, and am glad to see them moving onto DX11.
That's what I was afraid of: People thinking OpenGL is copying features from DX11. It's actually the other way around - Manufacturers create these new features (not Microsoft), and they show up as OpenGL extensions first.
Using OpenGL extensions, ATI cards supported hardware tessellation at least as far back as last August - before DX11 was even released. This update to the spec standardized the calls - any card manufacturer could have added support for them in OpenGL on any hardware before now (had nVidia actually released any cards with hardware tessellation).
