NVIDIA G80 Takes Unified Shader Approach
 

VR-Zone came to know that the future is actually pretty near where NVIDIA G80 design is based on unified shader architecture slated to appear in 2006. G70 already supports Longhorn WGF 1.0 API so most likely G80 will support WGF 2.0 with improved virtualization techniques and new pipeline stages. G80 design is completed and waiting for ATI R580 when the time comes.
