X-bit Labs had an interview with David Cummings, the Director of Product Marketing, Discrete Desktop Graphics at AMD's Graphics Products Group (formerly known as ATI). You can check it out over here.
X-bit labs: It is obvious that it is crucial to be the first with introduction of next-generation products. ATI was first-to-market with DirectX 9 generation and won the round, whereas Nvidia was first to introduce DirectX 10 GPU and won this time? Are you confident that you will be the first to launch DirectX 11 GPU?
David Cummings: Currently, we are the only vendor supporting DirectX 10.1, another first for us. As all features of DirectX 10.1 will be supported in DirectX 11, many developers are starting to develop for DirectX 10.1 as a preparation for the eventual move to DirectX 11. We feel very confident that we will make that transition to DirectX 11 right along with the developers.
