nVidia talks about next generation hardware: G80
 

An NVIDIA representative has given some interesting tidbits on the company's next-generation G80 graphics processing unit at the Morgan Stanley Semiconductor & Systems Conference.

The spokesperson stated that they're "increasing the flexibility of the programmability, enabling the artists to express themselves in a free way." That doesn't tell us a great deal about their hardware configuration, but they have stated that programmers will be able to express themselves by programming in a unified shader pipeline.
