Due to the press attention on the matter, AMD issued a statement that Huddy was merely speculating and that he doesn't have any special insight into Microsoft's DirectX roadmaps, which sounds weird considering Huddy is a high-ranking AMD employee.
“There have been reports based on a video of Richard Huddy of AMD making speculative comments around DirectX 12 support on versions of Windows. Richard Huddy does not speak for Microsoft, and he was unfortunately speculating from Microsoft’s publication of key dates and milestones for Windows 7 lifecycle and mainstream support policy. Richard has no special insight into Microsoft’s Windows or DirectX roadmaps. Microsoft is a key, strategic partner for AMD and we’re continuously collaborating with them on DirectX 12.”We'll have to wait on official news from Microsoft to clear up the matter but considering that mainstream support for Windows 7 ends in January 2015 it's rather unlikely that the operating system will get DirectX 12 support.
