oh wait, i found info freak:

NV30 will be a 0.13-micron chip produced at TSMC.
The NV30 architecture will be similar to R300 but with more features (e.g. more shader instructions supported), higher core clock speed and faster memory.
Although support for a multichip solution is built into NV30, the NV30 platform will be a single chip solution just like every other NVIDIA card.
NV30 taped-out just recently and is 3 - 4 months away from final production silicon.
NVIDIA will most likely launch NV30 before their November/December shipping dates much like ATI launched R300 and Matrox launched Parhelia.
Despite very low yields on the parts, NVIDIA will make sure that enough NV30 parts are available to meet demands for this year.
Realistically speaking, December will probably be the month that NV30 will be readily available.

If all goes as planned, NV30 will be a very worthy successor to the GeForce4
