I think that OpenGL as layer on top of DirectX is not necessarily a bad thing. Performance bottlenecks are usually either in GPU performance or in the bus bandwidth. Those places are not affected by the extra layer where OpenGL API will get translated into DirectX (that will happen before anything will go to GPU). Besides, from what I understand, ABI in Vista is significantly different from ealier version of Windows and DLL function call is not a huge performance hit anymore.

I guess we will see... I'm not in a rush of getting Vista either (so far Win98 can handle whatever doesn't work on Linux just fine), but Vista actually looks promising. It might be the first solid OS from Microsoft. I think they've brought many good people on board in the last 5-7 years and from developer perspective their attitude has changed and now the quality seems to be in pretty high regard. Hopefully it will pay out with Vista.
