I have found some more information about the NV36 from nVidia on NV News. If the information is correct it will be called GeForce FX 5700, and probally it will be avaible in Q3 of this year.
Made on IBM 0.13u, 82M transistors, 500Mhz core clock
256-bit memory bus, 325Mhz memory ( 128MB & 256MB versions as the NV31, probably )
Just as the NV35, marketing says it's a twice a NV31: thus, half the shader pipes of the NV35 ( no FX12, as in the NV35 )
Named GeForceFX 5700, taped-out in May, avaibility dates unknown
