This issue has been brought up at several ATI and nV 'chat sessions', and even up until 2 weeks ago, neither team had any comitted interest in adopting the feature to their products/drivers.
Also don't expect another 3D gaming card from Matrox, they let go their gaming relations people. Their focus is mainly 2D now, and light 3D. They may have a new 3D card, but it would likely be for 3D workstation work.
For the short term I don't expect anyone to adopt it. It's a great idea, and works well with many games (especially Morrowind IMO), but really the main focus for the next little while will be the next gen cards, and making them work, and squeezing all they can out of those. Towards the end of that cycle I would expect the 'extras' to come, just like the shader effects came for ATI. I would think PCI-EX would play well to this technology, but we shall see.
