Three lines sourced from the 178.15 reveal Nvidia's renaming plan and they are:
NVIDIA_G92.DEV_0615.1 = "NVIDIA GeForce GTS 150"
NVIDIA_G94.DEV_0626.1 = "NVIDIA GeForce GT 130"
NVIDIA_G96.DEV_0646.1 = "NVIDIA GeForce GT 120"
These suggest that the G92-powered cards (GeForce 9800 models) will be renamed to GeForce GTS 1x0, while the G94 and G96 cards (GeForce 9600, 9500s) will be known as GeForce GT 1x0. This new naming scheme, which should help with making Nvidia's card offer easier to grasp, is expected to be introduced in about two weeks.
