It doesn't look like they will. Only PD11.
See my thread. I've got a GTX560 with same rendering problems. I have to keep going back to 301.42 drivers to get PD9 to work.
The 306 and soon 310 drivers apparently are much better for games.
So if you got PD11, watch out for PD12 - cause you no longer get any support for PD11.
The rich get richer.
