But Microsoft isn't phasing out OpenGL. They've said that they (Microsoft)
aren't going to support anything past OpenGL 1.5, and that further
implementations and support will be up to the individual card manufacturers.
Their reason for this is that they're developing a new set of video drivers
that are going to add a whole new way of doing GPU programming, and it would
be a huge drain of time to support both DirectX 9/10 AND further
implementations of OpenGL, when the new setup is optimized specifically for
DirectX.
There's an article on GameDev.Net by one of the DirectX MVPs. He talks about
DirectX 10's architecture, and how it fits with Vista.
Here's the article: http://www.gamedev.net/reference/articles/article2280.asp

There is at least one thing that makes MS attempt to put down OpenGL performance inconceivable: very many CAD programs rely on OpenGL, and if OpenGL performance drops, CAD users will take notice, thus making Windows Vista a "not so good option for CAD users". The CAD users are quite many.. And don't tell me CAD programs "does not need the realtime experience like games" - try that statement on a young mechanical engineer/designer in your neighbourhood! Realtime if VERY important if you sit all day designing stuff..
