that's why I'll take the plunge into CineFX architechure with the refresh of GeForceFX - hopefully that will have, 256-bit bus (8x 32-bit or 4x 64-bit controllers) 2 texture units per pipeline, more vertex engines, etc.
A "refresh" isnt going to suddenly get 256 bit. I've been reading this on a number of forums and it's just wrong.
It would be a whole new chip as the pins would increase as well as the basic architecture of the chip. May as well be a whole new chips for that matter. The only way you might be able to hang a 256-bit label on the NV30 is if they can make a scalable, dual chip model, at which point you'd have 2x128 bit, and might be able to market this as 256 bit, the same way Atari marketed the Jaguar game console as 64 bit.
