Further speculation has recently surfaced in regards to ATI's upcoming R600 series GPU (their answer to NV's G80). Apparently its been discovered that this monster will in fact natively support Microsoft's upcoming DirectX 10.1 (due sometime during Q2 next yr).

Its also been made clear that DX 10.1 will carry a few notable enhancements over that of the embedded DX10 in Windows Vista, such as better multi-core support and an optimized API.
