I also noticed thet with the 9600 Pro they have released a 9800 Pro to take the place of the two discontinued retail 9800s. It is 4x AGP and 256MB, so G4 users still have an option for a high-performance card - it's getting older, but the 9800 can still satisfay all but the hard-core gamer.
I still think ATI needs to lower Mac-edition prices, but at least they're building cross-platform cards now; I can forsee the time in the nearish future when this becomes the norm.
Overall this 9600 is good for users of the G4 towers, since the dual link DVI port makes it the cheapest card that will run the 30" ACD - and the only one that works on a G4.
