The Register has a story on Microsoft pulling out of the OpenGL ARB:

Microsoft was a founding member of the Open GL architecture review board (ARB), and in a letter to ARB members seen by The Register, said it would pursue "focus our energies on improving and evolving our own Windows graphics platform", from mid-February.

So, what happens on the workstation platform? Opportunity for Linux to drive itself onto the desktop from on high, or a chance for Microsoft to start sealing off all GUI comers?
