I can't see them doing that.
Nope, doing so would in its self be quite risky, they may find users with dead, out of warranty cards using this as an excuse for a free replacement.
Especially as from what I can tell, there aren't any tell-tale signs from a card dying as a result of this driver. Unlike the 7950 issues MSI had (both TIM and diode issues) that could be easily identified and swapped out with minimal fuss.
I wonder how many different setups both AMD and Nvidia use to test drivers and to what extent? It strikes me as something that should be caught in early testing, but then again we don't know the full extent of the damage done.
Have Nvidia released a statement on this and pulled the drivers?
