"While NVIDIA remains extremely tight-lipped over its future products,
it is known that the company is readying its code-named NV47 visual
processing unit, a massively revamped GeForce 6 architecture with 24
pixel pipelines. The NV47 is expected to be released sometime in
Spring, 2005, but it is unknown whether NVIDIA is ahead, or behind
ATI's R520 product.

The status of NVIDIA's future architecture code-named NV50 is also
uncertain: some reported recently that the chip had been cancelled, but
officials decline to confirm or deny the information."
