DX10 came out November 30, 2006 - which gave DX10 devs geometry shaders
The OpenGL 3.2 spec was released 21 days ago (spec != drivers though!), which finally put Geometry shaders into the core specification. That's only, what, almost 3 years after DX developers got them.
So... if you need to use geometry shaders in your game, what GL extension do you code against? GL_EXT_geometry_shader4? GL_ARB_geometry_shader4? NV_geometry_program? or the core spec? Chances are you'll end up coding against all 4, because you can be absolutely certain most cards will support 1 of those extensions, but each card will probably support a different one.
If the Khronos group keep insisting that they must keep the OpenGL APi 3 years behind D3D10, it's not difficult to see why developers aren't all that keen to go with OpenGL. If the Khronos group continue to keep giving us information which they later back track on (like the entire OpenGL3 spec), it's not surprising to see game developers ditching OpenGL3 in droves. To see Carmack ditching OpenGL really shouldn't come as a surprise to anyone working with OpenGL3. I've worked with OpenGL for the past ten years or so, and I'm sad to say that I'm currently stripping all OpenGL out of our codebase in favour of the 'other' API. Currently it seems to be what every developer is doing at the moment. OpenGL is just a royal pita these days. Let it die.
