It is hard to believe that a man is telling the truth when you know that you would lie if you were in his place - H.L. Mencken
Vista comes out at the end of January and the Nvidia will be ready for that timeframe with the final driver. It just doesn't want to unnecessarily jump the gun and reveal some bugs while it has time to polish the driver before it lets it out.
Geforce 8800 GTX and GTS have a very good Windows XP SP2 driver and this is the OS where Nvidia keeps its focus at. Vista gaming is still to come and some frustrated G80 early Vista birds can only watch the card and cry. Not even aero works without Nvidia's help but the driver is on the way, some ten+ days to go, unless Nvidia delays it again.
Still, you should not worry about the driver as it hundred percent comes out for the end of January. As for DX10 games that is different story, you can run a DX 10 SDK and that's about it for the time being. µ
