Direct X 10 To Appear On XP?

There's a very interesting little news article in this month's UK edition of PC Format (October 2007, P.22). For the benefit of anyone who doesn't have access to this magazine, the article says that Nvidia has been having problems with "virtualised 3D memory" on its 8x00 series graphics cards and MS has now made this feature optional on DX10 and not required. Apparently this removes a major obstacle to getting DX10 to work on XP. The article states "there is now no technical reason why DirectX 10 can't be ported to XP".Interesting.In the same edition there is a review of World In Conflict, and they compare the DX9 and DX10 versions side by side. The review says the two versions are visually identical and no difference can be noted, although the DX10 version runs at a lower framerate.Interesting.There was another article in the same magazine towards the end of last year, where they interviewed both Nvidia and ATI representatives, and reps from various developers working on the first wave of DX10 titles. Some of the devs stated that they were using a special build of DX10 that runs on XP for developing their titles, and that there was no real reason why DX10 can't run on XP.
