I don't know the date but if you look at history, the ATI 3000's and Nvidia 8000's matured right before Vista release and the 4000's and 9000's came out about the same time as the launch. Win7 being right around the corner and back to school/holidays coming up means we'll probably see something in the 280s (290?) and 4870 (DirectX 11 ready)... which will be followed shortly after by the next gen.
I would cite regulation, but I know you will simply ignore it.
