During Ceatec in Japan this past week, ATI said that it expects to see DirectX 11 GPUs based on a 40 nm manufacturing tech sometime next year. DX11 is expected to bring several substantial advancements over DX10, including the introduction of Shader Model 5.0, as well as GPGPU support and multithreading support, both of which are essential for the graphics industry and the myriad of multi-core graphics cards that exist today. Also, hardware tessellation will be supported by DX11. Hardware tessellation has been supported by ATI cards going back to the 2000 series, but has never been popular with PC game developers. Tessellation, which allows for a low-polygon model to see a real-time increase in polygon density with minimal performance loss, was part of the GPU ATI designed for the Xbox 360, and with DX11, may finally be a feature utilized by PC game developers. While DX11 is expected to improve visuals over DX10, according to Ars Technica, the bulk of improvement is reserved for "...improving GPU computational capabilities and efficiency in a variety of environments." Now that the software will be in place, we may see the GPGPU become a widespread trend.
