That's very good news!
I never saw a statement by NVidia that support was dropped. On the contrary, Plagman stated
Recent ABI support for the 173 legacy driver series is still on the roadmap; it hasn't been dropped.
Hopefully the 96.xx.xx won't be forgotten either.
So all in all very good news. Of course i understand that these cards won't have top-priority anymore, and i certainly don't want to sound too pushy, but should we think about weeks or months?
