Sounds a lot like a few thousand A3 GPU boards will be shipped to consumers as is (March),
while they re-spin again in hopes of fixing whatever is causing all the trouble.
Its just rumour, but Charlie may be right about "hope TSMC fabs perfect huge chip vs respin adding redudancy like double via to make chip even bigger".
Very tough situation indeed. But unlike G200 which went with conservative 65nm, there is no "55nm" equivalent half-node shrink.. 40nm is already that!
One way or another nVidia needs to fix/work-around 40nm issues till end of '10.
